feat: add manual and automatic WARP IP rotation (#5099)

* feat: add manual and automatic WARP IP rotation

* fix: update generated api and frontend schemas

* fix(warp): validate rotation interval, fix auto-update timing, sync editor

- Validate the auto-update interval as an integer and store it via setInt;
  a non-integer value previously broke GetAllSetting for the whole panel.
- Seed warpLastUpdate when the interval is saved and when changing IP
  manually, so auto-update counts from "now" instead of epoch 0 and a
  manual rotation doesn't trigger an immediate scheduled one.
- Guard WarpIpJob: when lastUpdate is unset, establish a baseline and skip
  instead of rotating on the next tick.
- Log WARP license re-apply failures instead of swallowing them.
- After a manual "Change IP", sync the in-memory Xray editor with the keys
  the backend persisted so a later template save can't revert them; only
  toast success when the interval save actually succeeds.
- Add the WARP rotation UI strings to all 13 locales.
- Drop trailing whitespace introduced in entity.go and xray_setting.go.
