feat(wavelog): group log entries by pass session (satellite + AOS timestamp)

User request: logs should be separated by satellite/pass. Each pass
session gets an ID = satellite name + AOS timestamp (the second the
elevation hits 0, from OrbitalPass.aosTime), e.g.
"ASRTU-1-20260804-2014". Log page groups entries by session:
group title (satellite - local time) + thick divider line between
groups (md --- style); legacy entries without sessionId fall into
"Ungrouped" at the end.

- WavelogQso: +sessionId (persisted in queue JSON)
- LogTab: sessionId built from satelliteName + aosTimeMs (radar page
  passes currentPass.aosTime)
- WavelogLogScreen: grouped rendering + wavelog_ungrouped string (4 locales)
- sessionId UTC yyyyMMdd-HHmm; display converts to local time

Verified: check_strings OK (9 files); :app:compileDebugKotlin
BUILD SUCCESSFUL. Not released (batched).
