DEV: Improve generic import script (#25972)
* FEATURE: Import into `category_users` table * FIX: Failed to import `user_options` unless `timezone` was set * FIX: Prevent reusing original `id` from intermediate DB in `user_fields` * FEATURE: Order posts by `post_nuber` if available * FEATURE: Allow `[mention]` placeholder to reference users by"id" or "name" (username) * FEATURE: Support `[quote]` placeholders in posts * FEATURE: Support `[link]` placeholders in posts * FEATURE: Support all kinds of permalinks and remove support for `old_relative_url` * PERF: Speed up pre-cooking by removing DB lookups
