feat: node 22 and pnpm support - upgrade code and dependencies

[hcavarsan]

• Upgrade all dependencies
• Switch from npm to pnpm
• Ensure Node 22 is working
• Removed Google Analytics
• Removed Sentry
• Run pnpm lint, pnpm build, and pnpm dev successfully

Due to an Electron-Builder error, the pnpm build command requires a workaround. You'll need to add the following lines to your $HOME/.pnpmrc file:

node-linker = hoisted
public-hoist-pattern=*
shamefully-hoist=true
side-effects-cache=false

PS: tests and cypress need to be updated
