🗝️ fix: Resolve MCP Runtime User and Request Placeholders (#13626)
* fix: Resolve MCP Runtime User Placeholders

* fix: Harden MCP Runtime Placeholder Connections

* fix: Update MCP Source Tag Test Expectations

* fix: Complete MCP Runtime Placeholder Reinit

* fix: Harden MCP Request Scoped Runtime Configs

* fix: Align MCP OAuth Tests With Domain Policy

* fix: Harden MCP Runtime Resolution Edges

* fix: Avoid MCP Runtime Reprocessing Pitfalls

* fix: Reuse MCP Request Scoped Tool Discovery

* fix: Validate MCP Body Runtime Fields

* 🛡️ refactor: Harden runtime placeholder edges from review

- Warn at inspection when a trusted server URL contains runtime
  placeholders but no domain allowlist restricts the resolved target
- Document the three resolution sites that must stay in sync so the
  validated config always matches the connected one
- Note the per-call connect cost of ephemeral GRAPH/BODY connections
- Drop the no-op removeUserConnection in callTool's ephemeral cleanup;
  ephemeral connections are never stored, and removing the entry could
  orphan a still-connected cached connection after a config change

* 🪪 fix: Cover oauth_headers, Graph URL gating, and request-scoped reconnects

Address Codex review:

- Resolve runtime placeholders in oauth_headers (processMCPEnv + Graph
  pre-pass) and include the field in placeholder detection, so OAuth
  discovery/token requests no longer send literals; consolidate the
  detection field lists into one helper
- Defer the early domain gate when the URL still carries a Graph
  placeholder (resolved async later); the authoritative
  assertResolvedRuntimeConfigAllowed check still enforces policy
- Bypass the 10s reconnect throttle for request-scoped servers, which
  re-fetch tool definitions on every message by design
