buffs: cancel by spellID instead of GetPlayerBuff slot index

Browse Source 
`GetPlayerBuff(PLAYER_BUFF_START_ID + this.id, filter)` assumes the
visual index pfUI shows matches the engine's slot order. When that
mismapping happens — most easily reproduced by stacking buffs that
share a slot family — right-clicking one buff cancels another.

`C_Spell.CancelSpellByID(spellID)` ships CMSG_CANCEL_AURA keyed to the
spell, not a slot, so it's immune to whatever order the slot table is
in. Cache `spellId` on the button at refresh time in buff.lua; in the
unitframes/buffwatch handlers fetch the aura fresh via
`C_UnitAuras.GetAuraDataByIndex` at click time.

Fixes #10.
