* [Client] Improve card database update visibility
Addresses Cockatrice/Cockatrice#7431.
Cockatrice previously offered no in-client feedback while the card
database updater ran: the only progress UI lived in the first-run
wizard, stderr/stdout were not parsed in interactive runs, and starting
a second update with Oracle already open or with a hidden background run
active just showed a confusing 'already running' guard - even though
Oracle is launched as a separate process with no lifecycle tracking.
- Add a status-bar widget (CardDatabaseUpdateStatusBar) that appears
while an update runs and shows the Downloading/Parsing/Importing
stages with percent progress; it is also used in the quit-confirm
prompt so users see an unfinished update before cancelling it.
- Parse the updater's PROGRESS lines (new CardUpdateProgressParser,
unit-tested) in both foreground and background runs and log stage
changes to the new card_database.update category, throttled to at
most one line per second; forward Oracle stderr to the logs.
- Show a tray balloon when a background update starts and on finish or
failure instead of staying silent.
- Request a running Oracle instance to raise itself (QLocalServer
CockatriceOracleRaise-<user>) when the user starts another update, and
demote the 'already running' guard to an informative message only when
no running instance can be found.
- Emit download/scan/import progress unconditionally from Oracle so
interactive and background runs behave the same.
- Document the new log category in the troubleshooting guide.
