Stala's actions are now verified and confirmed, plus fixes for agent questions and candidate counts

Improved

• Stala confirms what she actually did After every scheduling action, Stala now shows a verified outcome block — built from a database read-back, not written by the model — so you can see exactly what was booked and when. A write that succeeded but couldn't be confirmed says so clearly, rather than reporting a failure.
• Agent questions are always readable and answerable When an AI agent asks you a question in chat, the message and options now scroll together with the Submit button always in view. A new maximise button fills the panel with the question so you can read and answer comfortably, then restore it in one click.
• Stala's questions now arrive as clickable options When Stala ends a turn by asking you something, the question now appears as a card with clickable answer options — so you always know the conversation is waiting on you and what it will accept as a reply. Stala also never returns a blank bubble.
• Candidate count on the jobs list shows active pipeline only The number next to each job now reflects only candidates still in your pipeline — not everyone who ever applied, including those rejected or withdrawn. The count now matches what you see when you open the job.
