The four right-pane buttons now work end-to-end (online happy path).
Each opens an AlertDialog wired to a ViewModel action; on success the
sheet closes and the customer card refreshes from the server.
- TerminalViewModel: + categories cache load (via CategoryRepository),
+ activeAction / actionInProgress / actionResult on the state. Action
methods (submitStamp, submitEarnPoints, submitRedeemStamps,
submitRedeemReward) all funnel through a runAction helper that toggles
in-progress, calls the LoyaltyApi, refreshes the customer on success,
surfaces failures inline.
- ActionSheets.kt (new): one ActionSheet entrypoint that dispatches by
ActionKind. Category multi-select via FlowRow + FilterChip pills.
EarnPoints accepts "12.50" / "12,50" → cents. Reward picker shows
available_rewards from the lookup response.
- TerminalScreen: action buttons enabled per state — stamp/earn stay
active offline (Phase E will queue them), redeem is hard-disabled when
offline per the plan ("redemption requires an internet connection").
Categories list comes from the cache filled at pairing; fresh refresh
runs in the background so newly-added categories show up next launch
without a manual sync.
Verified by ./gradlew assembleDebug — clean build.
