Proper guided character builder + level-up wizard

The bare name/class/level form left new characters as shells (1 HP, all-10
abilities, no proficiencies). Now creation and level-up are guided and auto-populate.

- Hand-authored progression tables (no SRD class/slot data exists on disk):
  src/lib/rules/{dnd5e,pf2e}/progression.ts — core classes' hit die/HP, key
  abilities, save & perception proficiencies, trained-skill counts, caster type;
  5e full/half/pact spell-slot tables, pf2e slot approximation; ASI/boost/skill
  schedules.
- src/lib/rules/progression.ts: getClassDefs/getClassDef, classSkillChoices/Count,
  buildCharacter() (HP from hit die + CON over levels, trained saves/skills, spell
  slots + ability), planLevelUp() (HP gain, new slots, ASI/boost/skill choices),
  applyIncreases/bumpRank. Pure + 12 unit tests.
- Multi-step CreationWizard (Basics → Abilities → Skills → Review) replaces the
  old form; pulls PF2e ancestry HP/speed from the bestiary; review previews HP/AC/
  saves/skills/slots; lands on a ready-to-play sheet.
- LevelUpModal reworked into a guided wizard: auto HP + spell slots, presents the
  level's actual choices (5e ASI/feat, pf2e ability boosts + skill increase) and
  applies them; keeps the strategic build-route advisor.

e2e helper drives the wizard; updated 7 specs to the new flow; new character-wizard
spec asserts a complete level-3 Wizard (HP 17, slots 4xL1 2xL2).
