fix+feat: morning QA fixes, worklist pagination, misc sidecar improvements

- caller-resolution: drop cache, use indexed phone filter (lead.contactPhone.primaryPhoneNumber.like)
- worklist: externalize page size (WORKLIST_PAGE_SIZE × WORKLIST_MAX_PAGES), paginate getMissedCalls/getAssignedLeads/getPendingFollowUps
- maint: unlock-agent, force-ready, backfill-caller-resolution, clear-analysis-cache, fix-timestamps
- ozonetel agent.service: force logout+re-login on "already logged in"
- ai chat: context expansion
- livekit-agent: updates
- widget: session handling
- masterdata: clinic list cache
