Fix unreachable mobile Settings link and raw error tracebacks

Settings lived inside .header-right, which is hidden below 600px,
leaving no way to reach it on mobile. It's now a standalone 44x44px
button next to the title.

Dashboard error cards showed raw Python/urllib3 exception strings.
Added a friendly_error() filter that classifies the failure (timeout,
connection refused, DNS, auth, 4xx/5xx, TLS) into plain-English copy,
with the raw string still available behind a details disclosure.
