refactor: parallelize bootstrap and simplify lifecycle with VueUse (#8307)

## Summary

Refactors bootstrap and lifecycle management to parallelize
initialization, use Vue best practices, and fix a logout state bug.

## Changes

### Bootstrap Store (`bootstrapStore.ts`)
- Extract early bootstrap logic into a dedicated store using
`useAsyncState`
- Parallelize settings, i18n, and workflow sync loading (previously
sequential)
- Handle multi-user login scenarios by deferring settings/workflows
until authenticated

### GraphCanvas Refactoring
- Move non-DOM composables (`useGlobalLitegraph`, `useCopy`, `usePaste`,
etc.) to script setup level for earlier initialization
- Move `watch` and `whenever` declarations outside `onMounted` (Vue best
practice)
- Use `until()` from VueUse to await bootstrap store readiness instead
of direct async calls

### GraphView Simplification
- Replace manual `addEventListener`/`removeEventListener` with
`useEventListener`
- Replace `setInterval` with `useIntervalFn` for automatic cleanup
- Move core command registration to script setup level

### Bug Fix
Using `router.push()` for logout caused `isSettingsReady` to persist as
`true`, making new users inherit the previous user's cached settings.
Reverted to `window.location.reload()` with TODOs for future store reset
implementation.

## Testing

- Verified login/logout cycle clears settings correctly
- Verified bootstrap sequence completes without errors
