predict + libdebuff + swingtimer: drop hardcoded spell data

Replace per-locale name tables and per-rank ID lists with single
canonical-rank lookups through C_Spell. Spell.dbc bits hoisted to
named constants at module top.

libpredict:
- Four 7-locale tables (PRAYER_OF_HEALING / REJUVENATION / RENEW /
  REGROWTH) collapsed to one C_Spell.GetSpellName(rank1id) call each.
- 25-entry SPELL_IDS (all ranks of Rejuv + Renew) for SPELL_GO_SELF
  HoT detection replaced by name comparison against REJUVENATION /
  RENEW. No per-rank ID maintenance.

libdebuff:
- GetSpellRecField(id, "name") → C_Spell.GetSpellName(id) at all call
  sites; the presence-guard pattern is gone (ClassicAPI is a hard
  dep, per memory).
- GetSpellRecField(id, "rank") → C_Spell.GetSpellSubtext(id).

swingtimer:
- Hoist FLAG_AUTOATTACK / ATTR_KEEP_SWINGS / ATTR_ON_NEXT_SWING to
  module-top constants via tonumber("0xNN", 16) so the SPELL_GO_SELF
  hot path stops re-parsing them on every call. Lua 5.0 has no hex
  number literals; strtoul-backed tonumber handles the "0x" prefix.
