v1.1.0: UI polish, LXMF messaging fixes, keyboard cleanup

- Remove boot display test (color bars + 1.5s delay)
- Show identity hashes on NodesScreen (colon-formatted, matching own identity display)
- Show node names in MessagesScreen and MessageView instead of raw hex
- Add message status indicators in chat (*/!/~ for sent/failed/queued)
- Fix LXMF send: retry Identity::recall() up to 5 times before failing
- Add LXMF logging throughout send/receive/queue drain
- Remove Alt+IJML arrow key mapping (obsolete with trackball)
- Filter own node from discovered nodes list
- Update troubleshooting docs with SetModulationParams STDBY fix
