fix: restore permission modal reactivity by replacing array mutation with new array creation

Previously, pendingPermissions was mutated in-place via .push(), causing
Svelte's reactivity chain to potentially receive the same array reference
and skip re-rendering the PermissionModal. Switching to spread syntax
guarantees a new reference on every update.

Also removed $state() from PermissionModal's local variables to match
the Svelte 4 reactive pattern used by other working components (Terminal),
avoiding rune-mode signal equality short-circuits.
