Add validation, deterministic AI generation, Supabase reconciliation, E2E harness, and observability

[Armand9999]

Motivation

• Harden runtime and CI quality for generated workout/meal features by adding validation, deterministic E2E fixtures, and safer OpenAI usage.
• Bring database schema into a reproducible migration and generated TypeScript contract to preserve existing production state and enforce Row Level Security.
• Improve operability with structured logging, health/readiness endpoints, typed Supabase helpers, and a Playwright-based E2E harness wired into CI.

Description

• Add strong input and domain validation and utilities: app/lib/date.ts, app/lib/profile.ts, app/lib/auth.ts, app/lib/generated-plans.ts, app/lib/definitions.ts, app/lib/profile-options.ts, and associated schema/type updates.
• Refactor generation and persistence to be non-destructive, validated, and testable with deterministic AI fixtures: app/lib/workout-generator.ts, app/protected/profile/meal-plan/action.ts, app/lib/e2e-ai-fixtures.ts, and app/lib/generated-plans.ts; use upsert/rpc and validate OpenAI responses before storing.
• Add observability and safety: structured redacting logger app/lib/logger.ts, GET /api/health and GET /api/readiness endpoints, improved error logging across layout/middleware/handlers, and safer auth callback handling with getSafeRedirectPath.
• Supply Supabase productionization artifacts and types: supabase/migrations/20260611170000_reconcile_fitness_schema.sql, supabase/preflight/..., app/lib/database.types.ts, supabase/config.toml, plus typed Supabase client/middleware/server helpers and cookie handling improvements in utils/supabase/*.ts.
• Add UX pages and flows for password recovery/reset and profile setup, plus small UI and accessibility fixes (NavBar image -> next/image, WorkoutTemplates date plumbing, WeeklyProgress date range keys).
• Add CI, local tooling, and E2E harness: scripts/check-env.mjs, playwright.config.ts, Playwright tests in e2e/, package.json scripts, .github/workflows/quality.yml, and test runner/TypeScript configs..env.example and .gitignore updated to document env usage and ignore artifacts.

Testing

• Added a comprehensive unit/test-suite under tests/*.test.ts and ran npm test locally; unit tests passed.
• Ran static checks locally with npm run lint and npm run typecheck, and a production build with npm run build; these succeeded.
• Configured Playwright E2E coverage with deterministic mocked-AI flows and an authenticated setup; CI workflow (.github/workflows/quality.yml) runs npm run env:check, npm run check, npm run build, and npm run test:e2e and uploads Playwright artifacts on failure.

Keep regeneration available for invalid meal plans

When an existing meal plan fails the new strict parser, this early return removes the New Plan button even though the message tells the user to generate one. Because getMeal() returns existing records without regenerating, any user with a malformed or legacy saved meals value is stuck on this error screen until the database row is manually changed; keep the regenerate action visible here or trigger regeneration for invalid saved plans.
