reze: Add Node.js password generator with memorable and random modes

Public password generator with no auth and no npm dependencies.

- Server-side generation using crypto.randomInt; two levels: diceware-style
  memorable passphrases (42abacus-91abdomen) and fully random characters.
- Configurable word list (EFF Large / EFF Short), digits per word, separators,
  capitalization, length, character class toggles, custom symbols and
  ambiguous-character exclusion.
- Light/dark theme matching druid520/site, entropy estimate and strength bar,
  clipboard copy, options persisted in localStorage.
- Dockerfile for Dokploy plus a Woodpecker deploy hook on trunk.
