Switch desktop appliction to Tauri instead of electron

[mr-zwets]

Checklist

• run the default app
• run the cashonize-vue codebase
• try the desktop build (windows)
• look into quasar/tauri crossover
• figure out the icons
• set mode to 'tauri'
• try the linux build
• make sure black flash on startup is solved
• make sure transition goes well regarding to install location and wallet state (no duplicate installs/new wallet data)

Extra

• try the android build

Tradeoffs

• easy .exe, nsis and msi targets
• much smaller nsis .exe output (3.7 MB vs 65.4MB)
• slower build time (1st time 12m 23s, 2nd time 87.35s)

Quasar usage

why using quasar + tauri instead of vue + tauri directly:

• $q.notify & $q.dialog
• { Dialog, Notify } from "quasar"
• bootfile for deep linking
• special setup for pinia store
• q-img, q-card-section, q-card etc, q-dialog
