Next.js 16 renamed middleware to proxy. Merged session-based auth and
API key auth into a single proxy.ts. Also fixed: auth route handler
exports, missing card component, Button asChild type errors, signIn
return type, Drizzle eq() type narrowing, and useSearchParams suspense
boundary.

- Add GET /api/auth/profile endpoint to expose user provider info
- Settings page fetches provider on load to detect credentials vs OAuth
- Credentials users: change password form (current/new/confirm) calling PUT /api/auth/password
- OAuth (Google) users: "Signed in via Google — password cannot be changed" message
- Client-side validation: min 8 chars, passwords-must-match before API call
- Success and error feedback displayed inline in the Security card

- Add X-User-ID header containing user.id to all fetch calls from proxy routes
- Updated routes: /api/predict, /api/predict/batch, /api/model/info, /api/model/load, /api/patterns/detect, /api/patterns/available, /api/training/start, /api/training/runs
- Enables user scoping on the FastAPI ML service side

Every data API route now filters SELECT, INSERT, UPDATE, and DELETE
queries by the authenticated user's ID, ensuring full multi-tenant
data isolation. Candle queries are scoped via chart_id ownership.

Implements task 6.3: deletes all user data in correct FK order
(span_annotations, annotations, candles, charts, span_label_types,
annotation_types) then deletes the user record. Returns 401 if not
authenticated, 200 on success.

Implements task 6.2: verifies current password with bcryptjs, rejects
OAuth users (no password_hash), validates new password (8+ chars),
hashes and persists the new password.

Create seedUserDefaults() helper in src/lib/db/seed-user-defaults.ts
that inserts default annotation_types (break_up, break_down, line) and
default span_label_types (bull_flag, bear_flag, etc.) scoped to a
given user_id. Call it from POST /api/auth/register after user insert
and from src/auth.ts Google signIn callback after new Google user creation.

Validates email presence and password length (8+ chars), checks email
uniqueness with 409 on conflict, hashes password with bcryptjs (cost 12),
inserts user into the users table and returns 201 with id/email/name.

Add sanitizeCsvCell() helper to both export routes that prefixes cell
values starting with =, +, @, or - with a single quote to prevent CSV
formula injection attacks.
Applied to:
- src/app/api/export/route.ts: timestamp and label_type columns
- src/app/api/span-annotations/export/route.ts: start_time, end_time,
label, and outcome columns
Closes task 4.10.

Validate that run_id matches /^[a-zA-Z0-9_-]+$ regex before interpolating into the API URL.
Returns HTTP 400 with 'Invalid run_id format' error if validation fails.
This prevents potential URL injection attacks and invalid identifier usage.

- May need to ensure candle data is float64/double type before processing
- Add GET /api/span-annotations/export endpoint for ML pipeline JSON/CSV export
- Add source and model_prediction fields to span_annotations schema

- GET /api/annotations accepts ?chartId= with fallback to most recent chart
- POST /api/annotations now requires chart_id in request body
- GET /api/export accepts ?chartId= to scope exported annotations
- DELETE /api/annotations supports optional chartId scoping
