fix: refresh entitlements after license create/delete

[ethanndickson]

Problem

When deploying a coderd_workspace_proxy (or other entitlement-gated resource) immediately after coderd_license in the same terraform apply, the proxy creation fails with:

Error: Feature not enabled

Your license is not entitled to create workspace proxies.

This happens because the provider fetches entitlements once during Configure() (before any resources are created) and never refreshes them. After coderd_license adds the license to the server, subsequent resources still see the stale pre-license feature flags.

Fix

After LicenseResource.Create() and .Delete() succeed, re-fetch deployment entitlements and update the shared CoderdProviderData.Features map. Since all resources share the same pointer, they immediately see up-to-date entitlements.

The refresh is best-effort: if re-fetching entitlements fails, a warning is emitted but the license operation itself still succeeds.

Regression test

Adds TestAccWorkspaceProxyResourceAfterLicenseInSameApply which starts an unlicensed Coder instance and applies a config that creates both coderd_license and coderd_workspace_proxy (with depends_on) in a single step — the exact scenario from the bug report.

Closes #303

Follow-up (previous comment had markdown formatting issues in shell):

Addressed the last Codex comment about unsynchronized shared feature cache updates in CoderdProviderData.

Implemented in fc2a6d6:

• Replaced mutable Features map field with an atomic snapshot (atomic.Pointer[featureSnapshot]) in CoderdProviderData.
• Added SetFeatures, Features(), and FeatureEnabled methods.
• Updated license create/delete refresh paths to call SetFeatures(...) instead of writing shared state directly.
• Updated entitlement read call sites (workspace_proxy, group resource/data source, and template) to read through the atomic accessors.

This keeps entitlement cache updates and reads race-safe under Terraform parallelism.
