Replace fixed-interval OnUpdate polls with C_Timer/RunNextFrame

Swap hand-rolled per-frame throttles for the modern timer primitives:

- turtle-wow: one-shot next-frame defer (self-hiding OnUpdate frame) -> RunNextFrame
- panel: clock, combat, and fps widgets -> NewTicker(1); guild roster -> NewTicker(60)
- minimap: coordinates text -> NewTicker(0.1)
- addonbuttons: one-shot init -> RunNextFrame; 5s button rescan -> NewTicker(5),
  guarded by IsShown() to preserve the old "paused while hidden" behavior

Ticker callbacks reference frames via upvalue since 'this' is unbound outside
OnUpdate. Genuine per-frame work (bar fills, fades, drag) and polls already
coordinated through pfUI.throttle are left as-is.
