fix(xray): sync routing rules when outbound tag is renamed (#5006)

* chore: ignore local .cursor directory

* fix(xray): sync routing rules when outbound tag is renamed

Renaming an outbound in the Outbounds tab only updated the outbound list, leaving routing rules pointing at the old tag. Propagate tag changes to routing rules, balancer selectors, and sockopt dialerProxy references, matching the behavior already used for balancer and WARP/Nord renames.

* test: mock HttpUtil to fix unhandled vitest rejections

* test(frontend): mock axios globally to prevent flaky network errors on CI

* test(frontend): fix eslint any errors in component test setup
