feat: client-side session search by name, date, and notes (2.4.0)

Add a search bar to the sessions list panel that filters rows in real time.
Searches display label, ISO date, month/year, and session notes. The count
badge updates to show matching/total; a no-results message appears when the
query has no matches.
