Wenxi b80667827f fix(plugins): manage default Chat selection in plugin settings (#16281)
## Description

Move MCP and OpenAPI default Chat settings out of Chat Preferences and
into Plugins. Chat Preferences keeps built-in controls and shows a
translated notice linking to Plugins.

OpenAPI Configuration now has an **Enable in default Chat** toggle.
Changes are saved with the form. Turning it off removes the plugin from
default Chat while preserving custom-agent use. OpenAPI tools remain
read-only; there are no per-operation switches. Admin directory status
reflects default Chat selection.

OpenAPI plugins no longer have a global disable control. Delete the
plugin to remove it from the workspace. Previously disabled records
remain off default Chat, but configured custom agents can use them,
subject to access and authentication. Explicit default Chat selection
normalizes the legacy flag. This uses existing fields and associations,
with no migration. New full-admin setup defaults the Chat toggle on;
scoped creators cannot change workspace Chat defaults.

MCP retains its server-level default Chat switch and global per-tool
controls. Removing the Chat Preferences cards intentionally removes
individual MCP tool selection specifically for default Chat. OpenAPI
retains its whole-plugin default Chat choice in Configuration.

Terraform `onyx_custom_tool.enabled` now controls default Chat
selection. The provider reads and writes `default_chat_enabled` through
the custom-tool API. Metadata and selection save atomically, parallel
resources preserve unrelated selections, and omitted OAuth settings
remain unchanged. Upgrade the provider alongside the server; older
versions use the removed global status writes. No Terraform state schema
migration is required.

Update the feature map and simplify the OpenAPI tools list to shared
name/description rows with consistent search and counts. Rows retain
composite method/path/name keys.

## How Has This Been Tested?

- 149 frontend tests passed across plugin forms, member details, and the
admin directory.
- Backend availability unit tests passed, including permission checks,
legacy selections, and omitted versus explicitly cleared OAuth settings.
Additional MCP/default Chat unit checks passed.
- 13 PostgreSQL tests passed against a disposable ODS database. Coverage
includes legacy OpenAPI construction, atomic API create/update/read,
rollback, and concurrent selections.
- Terraform provider `go test ./...` passed and generated documentation
is current. Live Terraform acceptance tests were not run.
- Repository pre-commit checks passed, including type checks,
formatting, lint, translations, and feature-map integrity. `git diff
--check` passed.
