* Migrate authentication from Clerk to BetterAuth (#322)
Replaces @clerk/react-router with self-hosted better-auth to eliminate
the external Clerk dependency and keep all user/session data in our own
PostgreSQL database.
**What changed**
- New: auth.server.ts (BetterAuth config w/ Drizzle adapter, bcrypt, Resend), auth-client.ts, api.auth.$.ts handler
- New: /login and /register pages with email+password and Google/Discord OAuth; open-redirect guard on redirectTo param
- New: UserMenu component replacing Clerk's UserButton
- Schema: sessions, accounts, verifications tables; emailVerified column; clerkId made nullable
- Migrations 0081 (BetterAuth tables) and 0082 (accounts extra columns for v1.6.9)
- All ~30 route files: getAuth → auth.api.getSession, isUserAdminByClerkId → isUserAdmin
- root.tsx: isAdmin read directly from session.user.isAdmin (no extra DB query)
- useDraftAuthRecovery: removed Clerk JWT refresh logic; replaced with cookie-session check
- models/user.ts: removed findUserByClerkId, findOrCreateUser, updateUserByClerkId (webhook pattern)
- Deleted: app/routes/api/webhooks/clerk.ts; uninstalled @clerk/react-router, @clerk/themes, svix
- scripts/migrate.mjs: extended with idempotent Clerk → BetterAuth data migration (FK conversion, email_verified, OAuth accounts)
- scripts/migrate-clerk-passwords.mjs: one-time script to import bcrypt hashes from Clerk CSV export
- BETTERAUTH_MIGRATION.md: dev and production runbooks
- All test mocks updated: vi.mock('~/lib/auth.server') instead of @clerk/react-router/server
- Test fixtures: added emailVerified field
**Follow-up (post-stable)**
- Rename actor_clerk_id column → actor_user_id in commissioner_audit_log
- Drop clerk_id column from users once migration confirmed

* Add .npmrc with legacy-peer-deps for better-auth/drizzle peer dep conflict
better-auth@1.6.9 declares peerOptional deps on drizzle-orm ^0.45.2 and
drizzle-kit >=0.31.4, but we run drizzle-orm ~0.36.3 / drizzle-kit ~0.28.1.
The adapter works correctly at runtime with our versions — the peer dep is
only for stricter type checking. This unblocks npm ci in CI without a risky
drizzle major-version upgrade.

Adds a Clone Season button on the admin sports season detail page. The
clone form pre-fills all settings with the source season's data, bumping
the year by one and shifting all dates accordingly. On submit, the new
season is created in a single transaction that copies participants,
scoring events (with dates shifted), futures odds/Elo rating stubs
(zeroed-out probabilities so the simulator can re-run), and QP config
for qualifying_points seasons.
Fixes#282
