Two bugs caused filters to show 0 and period selector to have no effect:
1. Python < 3.11 can't parse JS toISOString() Z suffix — every request with a
period filter threw ValueError → 500 → frontend received no data. Fixed with
_parse_iso() helper that replaces Z with +00:00 before fromisoformat().
2. 'All time' sends no from/to params, but backend defaulted to _month_start()
instead of omitting the ts filter. Fixed with _period_match() helper that
returns {} (no filter) when both from and to are absent.
Also: stale _user_mtd_cost reference in get_user route replaced with
_user_period_cost(user_id, None, None); adminApi types updated with from/to.

- New usePeriod hook (day/week/month/all/custom presets) with from/to ISO string outputs
- New PeriodSelector component (button group + custom date inputs)
- UsersTab, UsageTab, FocusGroupsTab all wired up with period state
- Backend /admin/users and /admin/focus-groups now accept from/to query params
- MTD Cost column header now reflects selected period label (e.g. "Cost (MTD)")
- Logout clears local state only (no account sign-out)

Backend:
- token_version in JWT (bump_token_version, get_token_version on User model);
jwt_required checks tv claim → 401 on mismatch; login routes embed version
- Quota pre-flight in all 3 LLM public methods (QuotaExceededError bubbles up)
- AI runner catches QuotaExceededError → sets status paused_quota + emits WS event
- Admin routes: POST /users (create), POST /users/<id>/reset-password,
POST /pricing, GET /focus-groups with aggregated cost; PUT /users/<id>
now bumps token_version on disable or role change
- backfill_usage.py: idempotent estimated-event generator for historical data,
tiktoken for GPT models, char/3.8 for Gemini, --dry-run flag
Frontend:
- 402 interceptor dispatches quota_exceeded CustomEvent
- adminApi: createUser, resetPassword, createPricing, listFocusGroups
- UsersTab: New User dialog + Reset Password in edit dialog
- PricingTab: New Price dialog (model, provider, input/output/cached prices)
- FocusGroupsTab: focus groups table sorted by total cost
- Admin.tsx: 4th tab (Focus Groups)
- FocusGroupSession: admin-only cost badge + dismissable quota exceeded banner

Backend: /api/admin/* blueprint with user CRUD (list, get, update,
disable/enable), usage summary aggregation (group by user/model/feature/
day/focus_group), usage event drill-down, and pricing list. Fixed
admin_required decorator (async-safe). Added find_all/count/update
helpers to User model.
Frontend: /admin page (AdminRoute guard, 3 tabs) — Users table with
search/filter/edit dialog, Usage tab with KPI cards + bar chart +
events table, Pricing tab showing active model rows with tier details.
Admin nav link visible only to admin role.
