Let each cooldown frame apply its own sweep settings

The sweep options reached the frames only through the cooldown module's
CooldownFrame_SetTimer hook, which set alpha 0 for a hidden animation and
SetReverse(true) for a reversed one. With that module disabled, Show Timer
Animation and Reverse did nothing, and reverse never turned back off
without a reload. The player buff sweeps had no other path at all.

Each owner now configures its own frame. Player buffs drive their
Cooldown with SetCooldown and Clear, and only while Show Timer Animation
is on. Unit frame auras, raid aura indicators and nameplate debuffs hide
the sweep with SetDrawSwipe and SetDrawBling. Every frame with a reverse
option calls SetReverse. The hook keeps the timer text and Hide Foreign
Cooldown Animations.

Nameplate debuffs hid the sweep with alpha, which the plate's SetAlpha
copied down on every target change (ClassicAPI keeps 1.12's alpha under
default plates), so hidden sweeps came back. Their settings now come from
UpdateDebuffConfig alone.

Bag slots get a native Cooldown like bank slots, in place of the
template's indicator Model, so Reverse Cooldown Animation covers bags and
Hide Foreign Cooldown Animations no longer hides them.

The buff, unit frame, nameplate and totem options apply without a reload.

Fixes #72.
