feat: SSE agent state, UCID fix, maint module, QA bug fixes

- Fix outbound disposition: store UCID from dial API response (root cause of silent disposition failure)
- SSE agent state: real-time Ozonetel state drives status toggle (ready/break/calling/in-call/acw)
- Maint module with OTP-protected endpoints (force-ready, unlock-agent, backfill, fix-timestamps)
- Maint OTP modal with PinInput component, keyboard shortcuts (Ctrl+Shift+R/U/B/T)
- Force-logout via SSE: admin unlock pushes force-logout to connected browsers
- Silence JsSIP debug flood, add structured lifecycle logging ([SIP], [DIAL], [DISPOSE], [AGENT-STATE])
- Centralize date formatting with IST-aware formatters across 11 files
- Fix call history: non-overlapping aggregates (completed/missed), correct timestamp display
- Auto-dismiss CallWidget ended/failed state after 3 seconds
- Remove floating "Helix Phone" idle badge from all pages
- Fix dead code in agent-state endpoint (auto-assign was unreachable after return)
