feat(rust): Admin → Rust servers page and the next wipe on the web (phase 16)

The module had no page for its own server rows: they were written only
through PUT /admin/rust/servers/:id, and the README described an
"Admin → Rust" server form that did not exist. D133 (org lead) builds it:
add, edit, test and delete a server, with the D130 wipe schedule in the
same form. The token stays write-only and an edit sends the stored
protocol back rather than re-stamping the row.

The next wipe shows on the server list and in the server page's header,
in the reader's own clock, marked "rescheduled" for a one-off date.
