Rework Terminal into a real live console; polish danger buttons and Settings

Terminal panel now opens a genuinely interactive shell (ttyd bound to a
unix socket, proxied through Unraid's own /logterminal/ nginx location —
the same mechanism Unraid's own Docker "Console" button uses) instead of
one-shot exec calls, shown inline with a Disconnect action; bash is the
default shell. Container/shell selectors and action buttons are now
correctly bottom-aligned (root cause: Unraid's theme puts a 10px margin
on every <button>, never reset before).

Destructive actions (Disconnect, Compose/Template Delete, Volumes/Images/
Networks Remove) get a consistent, solid red treatment at rest instead of
only tinting on hover, via new --bad-strong/--bad-contrast tokens.

Settings panel restructured: a real save toolbar instead of a button
buried in an empty-label row, card subtitles, a toggle switch instead of
a bare checkbox, and installed-package versions shown as chips.
