Wrap unresponsive tables in table-responsive (#131)

permissions.ejs (6 columns), users.ejs (3 columns incl. an inline
password-change form), and profile.ejs's domain-permissions table had
no .table-responsive wrapper, so on narrow/mobile viewports they'd
either overflow the page horizontally or force zoomed-out, unreadable
text instead of scrolling within the table. hosts.ejs already had the
wrapper — these three didn't.

Verified: EJS compiles, npm test 192/192 pass, and fetched each route
from a running instance to confirm the wrapper is present in the
served HTML.
