Compile the PWA help and account settings through Herb

Rails main compiles HTML templates through Herb under the 8.2 framework
defaults, which Campfire loads. Herb rejects `case` and its first `when`
in a single ERB tag, so the three pwa/ partials failed to compile, and
`herb:check` rejects ERB output in attribute names, which the account
settings' switch used for `checked`. Give `case` its own tag and build
the switch with tag.input; both render the same under Erubi.
