* feat: alternate search index for nimbus
Create an alternate search index for Nimbus that filters out
feature-flagged pages (equivalent to setting all feature flags to
false).
Notes:
- Creates two new DB tables, `page_nimbus` and `page_section_nimbus`,
which are filtered versions of `page` and `page_section`
- Makes `nimbus` versions of all the DB search functions
- Refactored the embedding upload script. Changes to make it faster (got
annoyed by how slow it was when testing...), incorporate retries, and
produce better summary logs.
- Upload script, when run with the environment variable
ENABLED_FEATURES_OVERRIDE_DISABLE_ALL, produces and uploads the
alternate search index
- Changed all the search calls in frontend/API to check for
`isFeatureEnabled('search:fullIndex')` to determine whether to search
the full or alternate index
* ci: produce nimbus search indexes on merge
* fix: turn full search index on
The end of the Great Migration is here!!!
Moves the last pages over, deleting pages like the FAQ that we don't use
and that contain duplicated information anyway.
Dev secret auth page URL had to change as App Router doesn't like the
leading underscores in the path.
Also fixes the not-found recommendations to use the proper Next.js
not-found page so it will return a 404 as it should. (I was under the
erroneous impression that I couldn't get the pathname in not-found.tsx,
that is not true, so this works better.)
