fix: resolve storage healthcheck path via LOCAL_STORAGE_PATH env var (#3004)

* fix: resolve local data directory to /app/data in production Docker

In the official Docker image, cwd is /app/apps/web (set via WORKDIR), but
the data volume is mounted at /app/data. Without pnpm-workspace.yaml present
in the runtime image, findWorkspaceRoot() returns null, so getLocalDataDirectory()
fell back to <cwd>/data = /app/apps/web/data, which the node user has no
permission to create. This caused the storage healthcheck to fail with
EACCES.

Add a production fallback: when cwd ends in apps/web, resolve the data
directory to two levels up (matching /app/data in the official image).

Re-resolves #2990.

* fix: replace apps/web heuristic with LOCAL_STORAGE_PATH env var

The previous fix special-cased a cwd ending in apps/web to land on /app/data,
but the heuristic could false-positive on any path with that suffix and was
fragile to Dockerfile changes. pnpm-workspace.yaml is never copied into the
runtime image, so the workspace-root walk was also dead code in production.

Replace the heuristic with an explicit LOCAL_STORAGE_PATH env var:
- Set LOCAL_STORAGE_PATH=/app/data in the Dockerfile (single source of truth).
- Add LOCAL_STORAGE_PATH to the env schema; storage and statistics services
  pass it through to getLocalDataDirectory.
- getLocalDataDirectory now uses the override when set, else workspace root
  (dev), else cwd/data.
- New Nitro plugin validates the resolved local data directory at startup
  and refuses to boot with a clear error if it isn't writable, surfacing
  permission issues immediately instead of at first upload/healthcheck.
- Document the new variable in .env.example and the Docker self-hosting docs.

* fix: address review feedback on storage path handling

- apps/web/plugins/2.storage.ts: use the default-import style for
  node:fs/promises (matches the rest of the repo, sidesteps any
  named-export concerns for fs.constants).
- packages/env/src/server.ts: reject relative LOCAL_STORAGE_PATH values
  via a zod refinement. Relative paths would be resolved against cwd,
  which differs between dev and Docker — exactly the same surprise the
  original bug had. Failing fast at config validation time gives a
  clear error before the server boots.
