Tin Chi Lo e9fd8fccdf fix(mcp): resolve responses-API tool dispatch by server_id and gate it on scope
The responses API surface still routed tool calls by server name. It built
the caller's reachable set as MCPServer objects, narrowed by both the key's
grants and the requested server filter, then discarded that identity by
flattening to display names. `tool_server_map` carried a name, and dispatch
re-resolved it with `get_mcp_server_by_name`, which walks the whole registry
and returns the first match. Server names are not unique, so a tool listed
from a reachable server could dispatch to a same-named server the caller
cannot reach, sending that server's upstream credential.

That is the bug this PR already fixed for MCP JSON-RPC, on the one surface
that had not been converted. The fix is the same: stop discarding identity.
`tool_server_map` now carries the server_id resolved within the caller's
reachable set through `resolve_tool_route`, the same scoped resolver the
JSON-RPC path uses, so a name two reachable servers share stays ambiguous
here too rather than silently picking one. Dispatch looks the server up by
id. A tool with no reachable owner fails closed and reports a result for its
tool call, matching how every other failure in that loop is surfaced, rather
than being dropped.

`resolved_server` is a parameter this PR introduced, and it let a caller
hand `call_tool` any server at all. That is the same class of defect one
layer down, so the check belongs at the chokepoint rather than at each
caller: `call_tool` now takes the reachable set the server was resolved
against and refuses to dispatch outside it, covering the caller's server and
one it resolves by name itself, which also walks the whole registry. Supplying
`resolved_server` without that set is rejected, so caller-supplied identity
always arrives with its provenance. Both callers already computed the set, so
nothing recomputes it.
