blinkagent[bot] d5296a4855 chore: add lint/migrations to detect hardcoded public schema (#21496)
## Problem

Migration 000401 introduced a hardcoded `public.` schema qualifier which
broke deployments using non-public schemas (see #21493). We need to
prevent this from happening again.

## Solution

Adds a new `lint/migrations` Make target that validates database
migrations do not hardcode the `public` schema qualifier. Migrations
should rely on `search_path` instead to support deployments using
non-public schemas.

## Changes

- Added `scripts/check_migrations_schema.sh` - a linter script that
checks for `public.` references in migration files (excluding test
fixtures)
- Added `lint/migrations` target to the Makefile
- Added `lint/migrations` to the main `lint` target so it runs in CI

## Testing

- Verified the linter **fails** on current `main` (which has the
hardcoded `public.` in migration 000401)
- Verified the linter **passes** after applying the fix from #21493

```bash
# On main (fails)
$ make lint/migrations
ERROR: Migrations must not hardcode the 'public' schema. Use unqualified table names instead.

# After fix (passes)
$ make lint/migrations
Migration schema references OK
```

## Depends on

- #21493 must be merged first (or this PR will fail CI until it is)
