client: missions screen — narrative, chips, chance bar, loot, abandon

Available missions now show description, type chip (colored by type),
success probability bar (green/gold/red), minLevel lock with 🔒.
Reward loot item displayed in footer. Active missions show reward
loot and an Abandon button (confirm dialog, −1 rep warning).
Result modal shows loot and fine details.
