### What changes were proposed in this PR?
Adds the metadata + access-control half of the model management API. Model
version upload and PyTorch
file validation follow in a separate PR.
- **Schema:** `model_user_access` table in `texera_ddl.sql` + idempotent
migration `sql/updates/31.sql` (changeSet 31).
- **`ModelResource`** (`@Path("/model")`)
| Method | Path | Description |
|---|---|---|
| POST | `/create` | Create a model; provisions LakeFS repo `model-{mid}`,
rolls the DB row back if repo init fails, grants the owner `WRITE`. Stores
`framework` (defaults `pytorch`) and `format`. |
| DELETE | `/{mid}` | Delete a model (owner-only): removes the LakeFS repo,
the S3 directory, and the row. |
| POST | `/update/name` | Rename (write access; validates name; rejects
duplicate). |
| POST | `/update/description` | Update description (write access). |
| POST | `/{mid}/update/publicity` | Toggle `is_public` (write access). |
| POST | `/{mid}/update/downloadable` | Toggle `is_downloadable`
(owner-only). |
| GET | `/list` | Models the user can access, plus public models. |
| GET | `/{mid}` | Get a model the user can read. |
| GET | `/public/{mid}` | Get a public model (unauthenticated). |
**`ModelAccessResource`** (`@Path("/access/model")`) — `owner/{mid}`,
`list/{mid}`, `grant/{mid}/{email}/{privilege}`, `revoke/{mid}/{email}` (all
write-access-guarded), backed by `model_user_access`.
- Both registered in `FileService`; storage/util layer reused unchanged.

### How was this PR tested?
New tests: `ModelResourceSpec` (22 — create/get/list/delete/update/toggle,
incl. access filtering, duplicate-name and forbidden paths, LakeFS-404 → 404)
and `ModelAccessResourceSpec` (28 — privilege helpers + grant/list/revoke).
Run: `sbt "FileService/testOnly *ModelResourceSpec *ModelAccessResourceSpec"` —
all green; `scalafixAll` + `scalafmtAll` clean.
