feat: enhanced search filters (#2398)

* advanced search filters

* improve labelId filtering in query

* index label ids on typesense

* index label ids on typesense

* filters on AI search

* refactor: detect typesense schema drift from the declared collection schema

* feat: show secondary search filters only when applied

Created by and Labels now stay hidden until they hold a value; a Filter
button at the right end of the bar lists the hidden ones and opens the
picked filter's dropdown immediately.

* fix: keep applied search filters in the order they were added

* feat: add title-only search mode

Adds a titleOnly flag to page search: the Postgres driver matches
titles via trigram-indexed unaccented LIKE ranked by word_similarity,
and a Match filter in the search spotlight switches between everything
and title-only matching.

* refactor: make title-only search a toggle chip

* fix: drop stale results when the search content type changes

* feat: add trigram index on attachment file names

* feat: extend title-only search to attachments

The titleOnly flag now matches attachment file names via the
separator-normalized trigram expression, and the toggle chip stays
available in attachment mode as File name only.

* refactor: keep the title-only label uniform across search modes

* feat: index txt attachments for content search

* feat: pin the current user at the top of the creator filter

* refactor: dim the you suffix in the creator filter

* feat: browse label-filtered pages without a query

Selecting labels now lists their pages newest-first before any text is
typed, on both the Postgres and Typesense drivers.

* fix: match any selected label instead of requiring all

* fix: use a gray spotlight selection instead of primary blue

* feat: include search results in the spotlight tab order

* feat: show last updated time on search results

* fix: stop empty-state flicker while the search query debounces

* feat: browse creator-filtered results without a query

Selecting a creator with an empty query now lists their pages (or
attachments in attachment mode) newest-first, with the same space and
page permission filtering as typed search.

* fix: show Untitled for pages without a title in search results

* quick page sharing fix

* minor search filter fixes
