Wizard navigates 5 steps (scope/condition/trigger/notify/review) with
per-step validation. form-state module is the single source of truth for
the rule form; initialForm/toRequest/validateStep are unit-tested (6
tests). Step components are stubbed and will be implemented in Tasks
20-24. prefillFromPromotion is a thin wrapper in this commit; Task 24
rewrites it to compute scope-adjustment warnings.
Deviation notes:
- FormState.targets uses {kind, targetId} to match AlertRuleTarget DTO
field names (plan draft had targetKind).
- toRequest casts through Record<string, unknown> so the spread over
the Partial<AlertCondition> union typechecks.

Promotion dropdown builds a /alerts/rules/new URL with promoteFrom, ruleId,
and targetEnv query params — the wizard will read these in Task 24 and
pre-fill the form with source-env prefill + client-side warnings.
AlertRow is reused by AllAlertsPage and HistoryPage. Marking a row as read
happens when its link is followed (the detail sub-route will be added in
phase 10 polish). FIRING rows get an amber left border.
Adds 6 lazy-loaded route entries for the alerting UI (Inbox, All, History,
Rules list, Rule editor wizard, Silences) plus an `/alerts` → `/alerts/inbox`
redirect. Page components are placeholder stubs to be replaced in Phase 5/6/7.
