Move SealShare onto Livewire Material

Replaces maryUI and daisyUI with nonameweb/livewire-material: the Vibrant
indigo scheme, a system/light/dark theme under sealshare-theme, one top
app bar with the account menu, the upload drop zone and link-ready
moments, M3 fields, dialogs instead of wire:confirm, snackbars instead of
flashed messages, a sortable admin table, and the starter-kit cleanup.
Docker builds assets after Composer; CI drops the Flux step.
