MiracleWatcher must be checked/reworked (possible game freeze or other errors)

Watcher can't use user dialogs and must not change game state. Looks badly. Must be researched and reworked to standard events:


Card example: [[Terminus]] Tests example: `testMiracleCost`

Start by locating MiracleWatcher and running the referenced testMiracleCost case for the Terminus example. Trace how the watcher handles dialogs and game-state changes, then compare that behavior with the project's standard events. Done means the watcher is reworked without user dialogs or direct game-state changes and the relevant test passes.
