The rails_failover middleware will intercept all `PG::ConnectionBad` errors and put the cluster into readonly mode. It does not have any handling for multiple databases. Therefore, an issue with the embeddings database was taking the whole cluster into readonly.
This commit fixes the issue by rescuing `PG::Error` from all AI database accesses, and re-raises errors with a different class. It also adds a spec to ensure that an embeddings database outage does not affect the functionality of the topics/show route.

Depends on discourse/discourse#20915
Hooks to the full-page-search component using an experimental API and performs an assymetric similarity search using our embeddings database.
Also:
- Normalizes behavior between logged in and anon,
we only show related topics in the related topic section
- Renames "suggested" to "related" given this only exists in related section
- Adds a spec section to ensure anon does not regress
- Adds `ai_embeddings_semantic_related_topics` to limit related topics
Renamed settings:
ai_embeddings_semantic_suggested_model -> ai_embeddings_semantic_related_model
ai_embeddings_semantic_suggested_topics_enabled -> ai_embeddings_semantic_related_topics_enabled
Plugins is still in an experimental phase and not much is overidden hence
avoiding adding site setting migrations.

Allows related topics to show up for logged on users
- Introduces a new "Related Topics" block above suggested when related topics exist
- Renames `ai_embeddings_semantic_suggested_topics_anons_enabled` -> `ai_embeddings_semantic_suggested_topics_enabled` (given it is only deployed on 1 site not bothering with a migration)
- Adds an integration test to ensure data arrives correctly on the client
