Disable the previous auto-share of conversation keys to newly-registered
devices: a stolen password / new device registered by an attacker no
longer automatically grants history access. Backup-Restore (which
restores the old device-id) still opens existing wraps as before.
Phase 1 of the approval replacement:
- New `lib/deviceApproval.ts`: realtime listener for `devices` INSERT,
surfaces a pending list, persists approve/deny decisions in
`chatapp.approvedDeviceIds` / `chatapp.dismissedDeviceIds`. Filters the
initial fetch by created_at > own-device's created_at so a freshly
installed client doesn't try to "approve" pre-existing devices.
- New `components/DeviceApprovalBanner.tsx`: bottom-right Discord-style
banner per pending request with Genehmigen / Ablehnen actions; reuses
`wrapForOneDevice` from conversationKeySync to fan out conv-keys.
- AppShell mounts both the listener and the banner.
Plus dev userData isolation in main.ts: when running unpackaged, append
`-Dev` to the userData path so `pnpm dev` runs side-by-side with the
installed packaged build instead of colliding on the single-instance
lock. Window title also distinguished as "ChatApp (Dev)".
