Dedup page: shorten paths, fix column alignment, per-row delete

- Strip the common /data/music/Library/ prefix from displayed keep/delete
  paths (every track lives there, so it added width without adding
  information); full path is still available via a hover title.
- Table now uses a colgroup with fixed column widths so headers stay
  aligned with their content regardless of how long a given path is,
  instead of drifting with the widest cell in the column.
- Add a per-row Delete button (self-contained form per cell) alongside
  the existing checkbox + bulk "Delete selected" flow -- the checkboxes
  now target an external form via the HTML `form` attribute instead of
  wrapping the table in a form, since a form can't legally nest another
  form for the per-row buttons.
