chore: update lance dependency to v7.0.0-beta.5

## Summary
- Update Lance Rust dependencies to `v7.0.0-beta.4` using
`ci/set_lance_version.py`.
- Update the Java `lance-core` dependency property to `7.0.0-beta.4`.
- Align LanceDB with dependency updates required by Lance 7, including
`object_store` 0.13 API compatibility.

Triggering tag:
https://github.com/lance-format/lance/releases/tag/v7.0.0-beta.4

## Verification
- `cargo clippy --workspace --tests --all-features -- -D warnings`
- `cargo fmt --all`

+        Creates a new permutation that will use ``connection_factory`` to reopen

+
+        The factory is a callable that takes a single argument — the base table
+        name — and returns a [LanceTable]. It must be picklable; the worker
+        will pickle it via standard ``pickle`` and call it to recover the base

+        picklable classes implementing ``__call__``. Lambdas and closures over

+
+        Setting a factory is necessary when the URI alone is not enough to
+        re-open the connection — most importantly for LanceDB Cloud (``db://``)
+        connections, where ``api_key`` and ``region`` aren't recoverable from
+        the connection object after construction.
+
+        For local file or cloud-storage paths the factory is optional: if not
+        set, ``__getstate__`` falls back to capturing
+        ``(uri, storage_options, namespace_path)`` and re-opening via
+        ``lancedb.connect(uri, storage_options=...)``.
