fix: bank display showing 1 instead of 0 + build fixes

- Removed 'e.bank||1' falsy trap (was converting bank 0 to 1)
- Fixed TypeScript errors: cp guard, unused vars, path aliases
- Added base: '/ui/' to vite config for correct asset paths
- Bank persistence already implemented (localStorage pedal-footswitch-bank)
- Rebuilt and deployed to src/web/ui-dist/
