fix(aprs): upload feedback, manual report reliability, station position

User testing round 3 (4.5.4): no success feedback on upload, aprs.fi
shows nothing, passcode calculator OK, notification present.

- Manual report now works even when service not running: ACTION_REPORT_NOW
  starts the service first (Toast "not configured" if missing callsign)
- Upload result feedback guaranteed: Toast always shows (short OK /
  long fail+reason), last result persisted (time/ok/detail) and shown
  in the settings card "Last report: HH:mm:ss OK/failed - detail"
- Position source: station position from settingsRepo (user decision)
  with live GPS last-known as fallback
- sendPacket reads the server confirmation line (short 3s timeout);
  server error text (Invalid/error) surfaces in Toast + card
- Strings EN/ZH/TR/IN/ID +4 keys
Verified: compileDebugKotlin all modules BUILD SUCCESSFUL,
check_strings 9 files OK.
