feat(calls): implement Linux LAN peer calls over SRTP

Reuse existing ChatHub consent and Podcast LibVLC capture for direct bidirectional H.264/AAC media, with embedded call controls and cleanup. Require HTTPS key exchange and reject IP-masking policies for this opt-in LAN/VPN transport.

Add native SRTP, signaling and lifecycle tests; document setup and remaining physical-device validation.

### Added
* [PostIt.Desktop/API] Add opt-in Linux LAN/VPN peer calls through the existing ChatHub, reusing Podcast LibVLC camera/microphone capture and H.264/AAC encoding with direct SRTP instead of HLS. Add consent, embedded local/remote video, hangup/interruption cleanup, private IPv4 validation and per-direction ephemeral keys over HTTPS-only signaling. Reject IP-masking accounts rather than silently bypassing TURN; keep this transport disabled by default and separate from the future Internet/group-call design. Test real bidirectional encrypted audio/video, wrong-key rejection, preview output, signaling and UI lifecycle; physical camera/two-machine rendering remains to validate.
* [PostIt/API] Begin Android/Linux call integration on the existing authenticated ChatHub: typed invitation, single-device consent, bounded SDP/ICE exchange and hangup; derive relay policy from account preferences and issue temporary coturn credentials. Attach the shared PostIt signaling client to the chat connection, end calls on disconnect/room departure/privacy activation, and add targeted regression tests. Calls remain disabled by default; native media adapters and Android/Linux end-to-end validation are not implemented yet.
* [PostIt] Clarify reuse of the existing ChatHub for call signaling and document the inconclusive Android native WebRTC experiment; discard the isolated laboratory without changing production chat or media behavior.
* [PostIt/API] Persist the account-level `HideIpAddressInCalls` preference (default false), expose it through the authenticated profile API and PostIt profile editor, and preserve it when older clients omit it. Prepare future TURN-only calls without enabling media transport yet.
