fix: box large PanelState variants to resolve clippy::large_enum_variant

Box LoginPanel, ConfigPanel, ThreadBrowser, McpPanel to reduce
enum size from 3792 bytes to 720 bytes (largest variant now).
Update as_any_ref/as_any_mut to use .as_ref()/.as_mut() for
all boxed variants, matching existing Plugin pattern.
Fix all construction sites across 8 files.
