refactor(providers): remove profile telemetry buckets

[johntmyers]

🏗️ build-from-issue-agent

Summary

Remove the static inference provider table and retire profile identity from provider lifecycle telemetry. Provider events continue to report operation and outcome, so adding an example YAML profile requires no telemetry registration or table row.

Related Issue

Refs #3906. This is a draft until the telemetry collector/report owner confirms that events without providerProfile are accepted alongside historical events with it.

Changes

• Remove the provider-profile telemetry enum and providerProfile parameter from the core event payload.
• Simplify provider create, update, and delete event emission without profile lookups or ID mapping. Keep existing success/failure outcomes.
• Remove the inference provider table, use openshell profile list for the imported catalog, and update the published telemetry description.

Deviations from Plan

The current main branch has no architecture/ directory, so the documentation update is limited to the relevant published docs. The plan comment was revised to reflect that.

Testing

• cargo test -p openshell-core --lib telemetry (11 passed)
• cargo test -p openshell-core --lib --no-default-features telemetry (2 passed)
• cargo test -p openshell-server --lib grpc::provider::tests (156 passed)
• mise run pre-commit
• mise run ci
• External collector/report compatibility confirmed by telemetry owner

The first mise run test attempt lacked local mke2fs; after installing it, a supervisor-network test timed out, including when run alone. The same test passed in the subsequent full mise run ci run. No e2e files or sandbox infrastructure changed.

Checklist

• Conventional Commit with DCO sign-off
• Published providers and telemetry docs updated
• Confirm downstream collector accepts the omitted field before merging
