Paragon: narrow weapon bypass; cascade talent ranks; Savage Defense

* Weapon-narrow: replace blanket EquippedItemSubClassMask bypass with an
  explicit allowlist (IsParagonWeaponSubclassWildcardSpell, currently
  Maelstrom Weapon 51528 only). Applied at all three gates: Player::
  HasItemFitToSpellRequirements, Player::CheckAttackFitToAuraRequirement,
  and Aura::IsProcTriggeredOnEvent. Maelstrom Weapon still procs from any
  weapon for Paragon, but Hack and Slash / Sword / Mace Specialization
  remain correctly weapon-gated.
* Talent ability-rank cascade: TeachLevelGatedAbilityChainNoPanel +
  CascadeRanksForTalentLearnSpellEffects walk the SPELL_EFFECT_LEARN_SPELL
  chain a talent rank grants and learn each rank up to the player's level.
  Wired into HandleCommit (on talent purchase) and OnPlayerLevelChanged
  (on level-up). Fixes Mangle (and any future LEARN_SPELL talent) being
  stuck at rank 1 because Player::learnSkillRewardedSpells is intentionally
  disabled for Paragon's class skill lines.
* Riding-skill gate for flight forms (IsParagonSpellAllowedByRidingSkill):
  Flight Form (33943) requires Expert Riding (34090); Swift Flight Form
  (40120) requires Artisan Riding (34091). Applied in PanelLearnSpellChain
  and TeachLevelGatedAbilityChainNoPanel so the cascade can't push past a
  rank the player isn't trained for. Also backticks `rank` in the level-up
  query (MySQL reserved word).
* Savage Defense (62600) on the panel: the SpellData bake's blanket
  SPELL_ATTR0_PASSIVE filter dropped Savage Defense even though Druid
  trainer 33 sells it at level 40. Bake (in fractured-tooling) now carves
  out a small PASSIVE_TRAINER_ALLOWLIST and the regenerated
  paragon_spell_ae_cost.sql + 2026_05_11_05.sql migration surface it on
  the Druid Feral spell tab.

+-- mod-paragon: surface Savage Defense (62600) on the Druid Feral spell tab
+-- of the Character Advancement panel.
+--
+-- The bake (tools/_gen_paragon_advancement_spells_lua.py) used to drop every
+-- SPELL_ATTR0_PASSIVE spell up front, even when the trainer explicitly sells
+-- it. That filter was correct for class-internal triggers (Feline Grace, etc.)
+-- but kicked out Savage Defense -- a passive that DRUID trainer 33 sells at
+-- level 40 (trainer_spell.sql line 2457). Bake now carves out a small
+-- PASSIVE_TRAINER_ALLOWLIST so legitimate trainer-taught passives survive.
+--
+-- The base file (data/sql/db-world/base/paragon_spell_ae_cost.sql) was
+-- regenerated alongside this migration so fresh deployments already have
+-- this row. Existing servers do not re-run base files on content change,
+-- so this update inserts the new (spell_id, ae_cost) pair idempotently.
+-- INSERT IGNORE keeps any per-row tuning a server operator may have already
+-- applied.
