fix: use aws-lc-rs instead of ring for remote HTTP and gRPC TLS (#4504)

## Summary

LanceDB's remote HTTP client (reqwest) and gRPC client (tonic) used
rustls with the `ring` crypto provider, while the AWS SDK and
object_store use aws-lc-rs. This moves both clients to aws-lc-rs:

- `tonic`: `tls-ring` → `tls-aws-lc`.
- `reqwest`: 0.12 → 0.13. reqwest 0.12 has no aws-lc-rs feature; 0.13's
`rustls` feature uses it. 0.13 was already in the lockfile through
object_store. No code changes were needed.
- `macos-system-configuration` is replaced by its 0.13 name,
`system-proxy`, which also reads the system proxy on Windows.
- `query` is now an opt-in feature in 0.13; it's used for request query
parameters.
- Certificate verification moves from `rustls-native-certs` to
`rustls-platform-verifier`, which uses the OS verifier on macOS and
Windows.

`ring` is still compiled in, because `lance-namespace-impls` and
`lance-namespace-reqwest-client` enable it through reqwest 0.12
(lance-format/lance#9855, lance-format/lance-namespace#369). Both
clients here pick aws-lc-rs explicitly, so they don't depend on which
providers are compiled in.

## Evidence

A temporary example that connects the remote client to real HTTPS hosts:

```
https://example.com:         Http error: ... 404 Not Found: <!doctype html>...   # TLS handshake OK
https://expired.badssl.com:  Hit retry limit ... connect_failures=3/3            # bad cert rejected
```

## Merge Risk

**Door:** two-way; dependency feature changes only.
**Blast Radius:** `remote` TLS and certificate verification (Python,
Node, and Rust LanceDB Cloud clients).
