feat: list platform files as table rows

Each file of a platform list is one row: name, folder, status chip, a short hash on a button that copies it whole, and a details cell. The details hold every declared hash, the size, the served copy and the readers. A reference's role is one word (glue, port, upstream, build) defined once in a legend instead of a phrase after every reference.

Visible words: Batocera 2,433 to 2,332, AmberELEC 1,301 to 1,299, RomM 1,607 to 1,596, RetroArch 2,207 to 2,088, RetroDECK arcade part 2 19,127 to 2,104. Rows weigh more Markdown, so 38 more systems move to pages of their own under the existing budgets.
