feat: add spell descriptions to tooltips via GetSpellDescription

Browse source 
Spell tooltips now show the spell description text (e.g., "Hurls a
fiery ball that causes 565 to 655 Fire Damage") in gold/yellow text
between the cast info and cooldown display.

New GetSpellDescription(spellId) C function exposes the description
field from SpellNameEntry (loaded from Spell.dbc via the spell name
cache). Descriptions contain the raw DBC text which may include
template variables ($s1, $d, etc.) — these show as-is until template
substitution is implemented.
