fix(rename): imperatively focus + select rename inputs

Svelte's native autofocus attribute is unreliable for inputs rendered
via conditional blocks (prior smoke-test fixed this for the new-list
input). Apply the same bind:this + $effect pattern to the list-rename
input (TasksScreen) and the workspace-rename input (SettingsScreen),
and select() the existing text so typing replaces the old name
cleanly.
