Interview emails now mention Stala, plus clearer HM review context and a sourcing page fix

Interview emails mention Stala's note-taking Confirmation and reschedule emails sent to candidates and interviewers now include a note that Stala, the AI interview assistant, may join to take notes. Candidates are given a clear way to opt out by contacting their recruiter before the session.
HM review inbox shows job ID and description age When reviewing sourced candidate shortlists, hiring managers now see each role's short Job ID — useful when multiple roles share the same title — and the date the job description was last updated, so you know if you're reviewing against the latest version.

Sourcing page no longer shows an error for expired searches Opening the sourcing view for a job whose saved candidate search had been deleted or expired was showing a red error. The page now quietly falls back to its empty state and recovers on its own.
