Merge branch '35627-api-response-for-adding-a-note-returns-http-400-for-command-only-notes' into 'master'

API requests creating command only notes should return 2xx responses

Closes #35627

See merge request gitlab-org/gitlab!19624

This changes the behaviour of note creation to respond with HTTP-202
when the note is command only - i.e. no note was created, but the
changes mentioned were applied.

The response type is also changed to expose the command changes,
allowing the client to verify that their commands were correctly
applied, and allowing the client to distinguish from real notes that
have been persisted to the database from command only responses with a
mechanism other than just checking the note id.

Be aware that as a result of this change the response from this service
will now return notes that have a null ID, a condition that previously
excluded.

This change addresses the need by:

* Update secpick to output which options are missing.

Fix smartcard config initialization

Closes #210596

See merge request gitlab-org/gitlab!27560

This allows dropping sidekiq jobs for the
`Namespaces::RootStatisticsWorker` when flipping the
`drop_duplicate_sidekiq_jobs_for_queue` feature flag.

This worker was already idempotent, this marks it as such so we can
deduplicate it later.

Full path search times out when searching all projects so
we only do this when the search space is already limited
by a group or user's authorized projects

Highlight line which includes search term is code search results

Closes #196384
