Fix verify-api.py: use correct API names throughout

Previous version had 14 failing checks due to wrong function names:
- Theme: load-preset with :keyword mode, not nonexistent load-default-*-preset
- Select: setf select-filter + select-filtered-options with 1 arg
- Dialog: push-dialog/pop-dialog + dialog-title on car of *dialog-stack*
- Mouse: make-box has no :x/:y initargs, use default constructor
- Framebuffer: draw-text on framebuffer-backend, not draw-text-on-fb
- Dirty: dirty-p, not component-dirty-p
- Theme functions in cl-tty.box package, not cl-tty.rendering

Also add ci-watchdog.sh for 15-min polling CI.
All 29 checks now pass.
