Repo MCP dialog ignores directory-level MCP status when default config has no `mcp`

[GammelSami]

In a repo, the "MCP for This Location" dialog can show:

even when directory-level MCP servers exist and are active for that repo.

Reproduce

1. Use a repo that has project-level MCP config (e.g. in repo config), while global/default config has no mcp section.
2. Open repo page -> MCP dialog ("MCP for This Location").
3. Observe empty state ("No MCP servers configured globally").
4. Verify backend/OpenCode returns directory MCP status for that repo directory (e.g. /mcp?directory=<repoPath> is non-empty).

Expected

Repo MCP dialog should show servers relevant for that repo/directory, even if global default config has no mcp.

Actual

Dialog derives server list from global/default config and shows empty state, despite directory-level MCP status existing.

Suspected cause

RepoMcpDialog uses config.content.mcp from default config to build serverIds, instead of deriving from repo-assigned config and/or directory-scoped MCP status.

Suggested fix

• Resolve config by repo (repo.openCodeConfigName) rather than always default.
• Build displayed server list from union of:
  • configured MCP servers for the repo config
  • keys from directory-scoped MCP status response
• Adjust empty-state text to distinguish "no global MCP configured" vs "no MCP for this repo".
