refactor: update TogglePanelAndFocus to use open/focused flags

Update TogglePanelAndFocus and related components to use open/focused flags.

Changed TogglePanelAndFocus from currently_open to open+focused flags.
Parser accepts optional [open] [focused] arguments.

Interactive mode toggles between open+focus and closed/unfocused.

Keymap updates: F/C/V in panel modes close panels when focused.

Model initialization: Virtual categories _Index/_Dim default to None
axis, regular categories auto-assign Row/Column/Page.

App test context updated with visible_rows/visible_cols.
