Exposes the per-key user-set flag on the experimental MCP server config
endpoints. CreateMCPServerConfigRequest and UpdateMCPServerConfigRequest
gain CustomHeadersUserKeys; MCPServerConfig returns the list so the
admin and user settings UIs can render it.
Validation:
- custom_headers_user_keys is rejected unless auth_type == custom_headers.
- Entries must be non-empty after trim, deduped case-insensitively, and
disjoint from the admin-set custom_headers map (HTTP header names are
case-insensitive per RFC 7230).
- custom_headers auth now requires at least one admin header or one
user-set key (the honcho.dev use case is only user keys).
- Updates that change admin headers re-validate any unchanged user keys
against the new admin map.
- The auth-type-change switch clears custom_headers_user_keys for any
destination other than custom_headers.
Also adds codersdk types MCPServerUserHeaderValues and
UpdateMCPServerUserHeaderValuesRequest plus three client methods
(MCPServerUserHeaderValues, UpdateMCPServerUserHeaderValues,
DeleteMCPServerUserHeaderValues) targeting the routes added in the next
commit.
