Add a 'Type' column to the Queue table mapping each job kind to a friendly
label, so downloads, copies, PS1 conversions, UMD dumps and save syncs are
distinguishable at a glance.
refresh_item matched the grid row by object identity, which silently fails
when the library list was rebuilt (background scan/store refresh) while the
scrape dialog was open. Match by release_id + system as a fallback, like
update_item_label already does, so the cover tile updates without a Reload.
- _on_ps1_convert now opens the Queue tab so the user sees the conversion
job start when converting from the Library or PS1 tab.
- Add a 'PS1 category (Category Lite)' setting (ps1_category) alongside the
existing ISO category; PS1 EBOOTs copy to /PSP/GAME/<category>/<ID>/
when set, matching the ISO category behaviour.
