e2e: character page spec, verified against a live server

- player card shows the mock character (name, class, level, XP)
- add a spell via a vacant slot, undo with Ctrl+Z, redo with Ctrl+Y
- remove a spell empties its slot back to vacant
- a prepared spell survives a reload (autosave round trip)
- attune an item, reload keeps it, clear empties the slot
