* fix(mcp): let MCP tokens call preview run tools (jobs:run scope)

The MCP proxy mints an internal JWT scoped to exactly `scope_for_route`
for the endpoint it forwards to. For preview run routes
(`run/preview`, `run/preview_bundle`, `run/preview_flow`,
`run_wait_result/preview`, `run_wait_result/preview_flow`),
`determine_kind_from_route` matched the `SCRIPT_JOBS` prefix
`jobs/run_wait_result/p` (because "preview" starts with "p") and derived
`jobs:run:scripts`. But the preview handlers run arbitrary request-supplied
code with no deployed path and require the broad `jobs:run` scope, so
`jobs:run:scripts` was rejected with 403 "Required scope: jobs:run".

Preview/bundle routes now carry no runnable kind, so the derived scope is
the broad `jobs:run` the handlers expect. This also aligns the route-level
access check with the handler check for these routes.

Fixes GIT-920

* fix(mcp): anchor preview-route match to endpoint segment

Address CI review: `route_path.contains("preview")` also matched by-path
runs of a deployed runnable whose path contains "preview" (e.g.
`jobs/run_wait_result/p/f/team/preview_report`). Since determine_kind_from_route
also feeds check_route_access, such a route would derive the broad `jobs:run`
and reject a legitimately kind-scoped `jobs:run:scripts:*`/`jobs:run:flows:*`
token with 403.

Anchor the exception to the actual preview endpoints
(`jobs/run/preview*`, `jobs/run_wait_result/preview*`) so by-path runs keep
their kind. Add regression tests for preview-named by-path paths, and trim
the comments per AGENTS.md.
