fix(palette): auto-focus input via set_next_window_focus + apply(theme) + try/except for actions

Added imgui.set_next_window_focus() on open so the palette window itself gets focus. The input field then gets focus on the next drawn widget. Wrapped action calls in try/except so a buggy command does not break the imgui.end_child/end pairing (was causing IM_ASSERT crash). Fixed theme_2 calls: apply_dark_theme and apply_light_theme do not exist; use theme_2.apply(palette_name). switch_to_dark_theme uses apply 10x Dark. switch_to_light_theme uses apply ImGui Light. switch_to_nerv_theme uses apply NERV instead of apply_nerv() from src.theme_nerv.
