Brues 2a562e0550 Make ClassicAPI the source of truth for non-player aura timing
ValidateAura resolved remote aura timers from libdebuff's allBuffAuras and then
from AllCasterAuraTracking via FindAllCasterAuraByName. Both existed for one
reason: vanilla cannot report a timer for an aura on a unit other than the
player. ClassicAPI's Aura::Source cache does, reconstructing duration and
expirationTime for any unit from the observed SMSG_SPELL_GO -- caster-modified,
so talent extensions and combo-point finisher scaling are already applied, and
Carnage's roll-gated Rip/Rake refresh is handled in the DLL rather than mirrored
in Lua.

Replaced that ~70-line cascade with ResolveUnitAuraViaClassicAPI, a positional
C_UnitAuras.UnitAura scan over the relevant range. Matching stays ours -- by
spellID when the conditional supplied a number, else by lowercased name, since
C_UnitAuras' own by-name lookup is case-sensitive and exact and would miss
[debuff:thunder_clap]. It runs after the existing scans and overrides them, which
is what "source of truth" means here.

Also drops the libdebuff UnitBuff timeleft bug the old comments worked around
(timeleft reporting ~1000s), since nothing reads it on this path any more.

Presence and stacks from C_UnitAuras are reliable. Timing is best-effort by
design: an aura cast before login, or one refreshed at max stacks, yields no
expirationTime, and remaining is left nil so the caller keeps its found-and-0
default. A permanent aura (duration 0) reports -1, matching the existing
convention.

Still on the old machinery and not yet migrated: the non-player overflow-slot
buff path (AllCasterAuraTracking, guarded by a debuff-slot check) and the player
branches. AllCasterAuraTracking still has 56 references across 5 files, mostly
OverflowBuffFrame and Conditionals.
