[Client] Improve card database update visibility (#7458)

* [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.

* [Client] Address card database update review feedback

* [Client] Add setting to control card database update tray notifications

* [Client] Address remaining card database update review nits

- Rename card_update_progress_parser.{h,cpp} to card_update_progress.{h,cpp}
- Store the CardUpdateProgress struct in the status bar widget

* Lint.
