New Album, Rename Album, New Smart Album, Merge Keywords and the text
prompts (rename a preset or a version, …) had Rename Keyword's bug:
their field took the focus back on every frame, so egui never reported
the focus Return gives up, and Return did nothing; only OK confirmed.
All six now use one `dialog_field`: a shared text field that keeps the
focus except while its own menu has it, opens with its text selected
and reports Return. They get the Cut / Copy / Paste / Select All menu.
