feat: add personajes page with level tracking and fix timer reactivity

- New /personajes page with CRUD for characters (name, class, level)
- Level editable inline, deletable (blocked if has active sales)
- ventas.html now loads characters list as datalist suggestions
- Fix timer: add reactive 'now' property so countdown updates
- Fix script loading: add defaults.js + app.js to ventas/personajes
- Fix table auto-reload: use loadCharacters()/loadSales() after mutations
- Timer now uses setTimeout recursion + visibilitychange handler
