Tin Chi Lo c612cd25f7 feat(mcp): enforce delegated-user ceiling for agent-OBO tool calls 
A delegated (agent-on-behalf-of-user) MCP tool call was ceiling-enforced
only against the agent key, so a delegated run could reach any tool the
agent could, regardless of what the triggering user is allowed.

check_tool_permission_for_delegated_user runs in pre_call_tool_check right
after the existing key/team check. Because the agent's ceiling is already
enforced there, additionally requiring the delegated user to permit the
server and tool makes the effective permission the intersection of the two
principals. A non-delegated call early-returns and is byte-identical.

The delegated user's reach is resolved across ALL of their auth contexts
(their own object-permission plus one per team they belong to) and unioned,
so a user whose MCP access is granted directly, through toolsets/access
groups, or through team/group membership is counted rather than
under-counted. resolve_delegated_user_contexts builds the contexts (reusing
the fail-closed reload_admitted_user for the own context); the same
get_allowed_mcp_servers / get_allowed_tools_for_server primitives the key
path uses run per context, so no permission logic is duplicated. Only a
context that actually reaches a server contributes its tool grant, so a
team that cannot reach a server does not leak allow-all for it. Fail-closed
throughout; reload_admitted_user is promoted to public for the reuse.

Part of LIT-4448 (build item 4).
