DEV: Fix png optimization test flakyness (#19535)
* DEV: Fix png optimization test flakyness

Update fixture with oxipng 7

This test broke when the pngoptimizer got better so the pre-optimized png in the fixtures was compressed further on upload creation, breaking the expected size.

PERF: stop downloading images from post processor and lean on uploads
Previously we would unconditionally fetch all images via HTTP to grab
original sizing from cooked post processor in 2 different spots.

This was wasteful as we already calculate and cache this info in upload records.

This also simplifies some specs and reduces use of mocks.

FIX: Issues with custom icons in themes (#13732)
Fixes two issues:
- ignores invalid XML in custom icon sprite SVG file (and outputs an error if sprite was uploaded via admin UI)
- clears SVG sprite cache when deleting an `icons-sprite` upload in a theme

FIX: Allow SVG uploads if dimensions are a fraction of a unit (#13409)
* FIX: Allow SVG uploads if dimensions are a fraction of a unit

`UploadCreator` counts the number of pixels in an file to determine if it is valid. `pixels` is calculated by multiplying the width and height of the image, as determined by FastImage.

SVG files can have their width/height expressed in a variety of different units of measurement. For example, ‘px’, ‘in’, ‘cm’, ‘mm’, ‘pt’, ‘pc’, etc are all valid within SVG files. If an image has a width of `0.5in`, FastImage may interpret this as being a width of `0`, meaning it will report the `size` as being `0`.

However, we don’t need to concern ourselves with the number of ‘pixels’ in a SVG files, as that is irrelevant for this file format, so we can skip over the check for `pixels == 0` when processing this file type.

* DEV: Speed up getting SVG dimensions

The `-ping` flag prevents the entire image from being rasterized before a result is returned. See:

FIX: Be able to handle long file extensions (#12375)
* FIX: Be able to handle long file extensions

Some applications have really long file extensions, but if we truncate
them weird behavior ensues.

This commit changes the file extension size from 10 characters to 255
characters instead.

See:

https://meta.discourse.org/t/182824

* Keep truncation at 10, but allow uppercase and dashes

FIX - use ImageMagick to determine size of svg images (#12230)
SVG files can have dimensions expressed in inches, centimeters, etc., which may lead to the dimensions being misinterpreted (e.g. “8in” ends up as 8 pixels).

If the file type is `svg`, ask ImageMagick to work out what size the SVG file should be rendered on screen.

NOTE: The `pencil.svg` file was obtained from https://freesvg.org/1534028868, which has placed the file in to the public domain.

FIX: should_alter_quality should respect png_to_jpg_quality (#12055)
`convert_to_jpeg!` is only called if `convert_png_to_jpeg?` and/or `should_alter_quality?` is true.

`convert_png_to_jpeg?` can be disabled by setting `SiteSetting.png_to_jpg_quality` to 100.

However, `should_alter_quality?` could be true if `SiteSetting.recompress_original_jpg_quality` was lower than the quality of the uploaded file, regardless of file type.

This commits changes `should_alter_quality?` so that uploaded png files will use the `SiteSetting.png_to_jpg_quality` value, rather than ``SiteSetting.recompress_original_jpg_quality` value.

FIX: Consider webp a supported image format for upload (#9015)
* Also fixes an issue where if webp was a downloaded hotlinked
  image and then secure + sent in an email, it was not being
  redacted because webp was not a supported media format in
  FileHelper
* Webp originally removed as an image format in
  https://github.com/discourse/discourse/pull/6377
  and there was a spec to make sure a .bin webp
  file did not get renamed from its type to webp.

  However we want to support webp images now to make
  sure they are properly redacted if secure media is
  on, so change the example in the spec to use tiff,
  another banned format, instead

FEATURE: Automatically generate optimized site metadata icons (#7372)
This change automatically resizes icons for various purposes. Admins can now upload `logo` and `logo_small`, and everything else will be auto-generated. Specific icons can still be uploaded separately if required.

## Core

- Adds an SiteIconManager module which manages automatic resizing and fallback

- Icons are looked up in the OptimizedImage table at runtime, and then cached in Redis. If the resized version is missing for some reason, then most icons will fall back to the original files. Some icons (e.g. PWA Manifest) will return `nil` (because an incorrectly sized icon is worse than a missing icon). 

- `SiteSetting.site_large_icon_url` will return the optimized version, including any fallback. `SiteSetting.large_icon` continues to return the upload object. This means that (almost) no changes are required in core/plugins to support this new system.

- Icons are resized whenever a relevant site setting is changed, and during post-deploy migrations

## Wizard

- Allows `requiresRefresh` wizard steps to reload data via AJAX instead of a full page reload

- Add placeholders to the **icons** step of the wizard, which automatically update from the "Square Logo"

- Various copy updates to support the changes

- Remove the "upload-time" resizing for `large_icon`. This is no longer required.

## Site Settings UX

- Move logo/icon settings under a new "Branding" tab

- Various copy changes to support the changes

- Adds placeholder support to the `image-uploader` component

- Automatically reloads site settings after saving. This allows setting placeholders to change based on changes to other settings

- Upload site settings will be assigned a placeholder if SiteIconManager `responds_to?` an icon of the same name

## Dashboard Warnings

- Remove PWA icon and PWA title warnings. Both are now handled automatically.

## Bonus

- Updated the sketch logos to use @awesomerobot's new high-res designs

Sam 766e67ce57 FEATURE: introduce lossy color optimization on resized pngs
This feature ensures optimized images run via pngquant, this results extreme amounts of savings for resized images. Effectively the only impact is that the color palette on small resized images is reduced to 256.

To ensure safety we only apply this optimisation to images smaller than 500k.

This commit also makes a bunch of image specs less fragile.

Sam 86255faa08 FEATURE: do not switch to JPEG unless you meet 75k byte savings
This also adjusts the algorithm to expect

- 30% saving for JPEG conversion

AND

- Minimum of 75K bytes saved

The reasoning for increase of saving requirements is cause PNG may have been
uploaded unoptimized, 30% saving on PNG is very possible
