Reconcile schema with migrations and fix failed migration

Browse Source 
- Align schema.prisma with add_15_features migration (15 discrepancies):
  nullability, column names, PKs, missing/extra columns, onDelete behavior
- Make universal_apply_programid migration idempotent for safe re-execution
- Add reconciliation migration for missing FKs and indexes
- Fix message.ts and mentor.ts to match corrected schema field names

-- Universal Apply Page: Make Project.roundId nullable and add programId FK
-- This migration enables projects to be submitted to a program/edition without being assigned to a specific round
-- NOTE: Written to be idempotent (safe to re-run if partially applied)
-- Step 1: Add Program.slug for edition-wide apply URLs (nullable for existing programs)
ALTER TABLE "Program" ADD COLUMN "slug" TEXT;
CREATE UNIQUE INDEX "Program_slug_key" ON "Program"("slug");
ALTER TABLE "Program" ADD COLUMN IF NOT EXISTS "slug" TEXT;
CREATE UNIQUE INDEX IF NOT EXISTS "Program_slug_key" ON "Program"("slug");
-- Step 2: Add programId column (nullable initially to handle existing data)
ALTER TABLE "Project" ADD COLUMN "programId" TEXT;
ALTER TABLE "Project" ADD COLUMN IF NOT EXISTS "programId" TEXT;
-- Step 3: Backfill programId from existing round relationships
-- Every project currently has a roundId, so we can populate programId from Round.programId
-- Only update rows where programId is still NULL (idempotent)
UPDATE "Project" p
SET "programId" = r."programId"
FROM "Round" r
WHERE p."roundId" = r.id;
WHERE p."roundId" = r.id
AND p."programId" IS NULL;
-- Step 4: Verify backfill succeeded (should be 0 rows with NULL programId)
-- If this fails, manual intervention is needed
-- Step 4: Handle orphaned projects (no roundId = no way to derive programId)
-- Assign them to the first available program, or delete them if no program exists
