fix: Resolve Firefox input issues and persist advanced filters (#14781)

# Pull Request Template

## Description

This PR fixes a few issues in Global Search and removes a non-functional
control.

* Fixes an issue in Firefox where characters could be dropped while
typing in the search input. The search now uses the latest input value
directly, preventing searches from running one character behind.

* Removes a stale query sync in `SearchHeader` that could overwrite
recently typed characters during the debounce window, causing the input
to appear out of sync.

* Fixes advanced search filters being removed from the URL on page
reload. The search page now waits for account data to load before
parsing URL parameters, ensuring agent, inbox, and date range filters
are preserved.

* Removes the non-functional "Sort by relevance" button from the search
tabs bar, as it was disabled and had no effect.
