* aerc: fix per-account extraConfig section names
The aerc configuration file `aerc.conf` can contain 10 different
sections, but only the UI section supports what the aerc manual calls
contextual configuration. This works by appending to the section heading
either `:account=name` or `:folder=bar`.
The aerc-accounts module, however, applied `mkAccountConfig` to each
section heading declared in
`config.accounts.email.accounts.<name>.aerc.extraConfig.*`. This means
home-manager will generate files with `[general:account=default]` and
the options will not be recognized by aerc.
To address this, and since it doesn't make sense for other sections to
only be under a single account's scope, an assertion has been added
to confirm that only sectons that support contextual config (i.e.,
only the UI section) is declared.
This also addresses confusions like declaring
`accounts.email.accounts.*.aerc.extraConfig.general.unsafe-accounts-conf
= true` and triggering a warning message because
`programs.aerc.extraConfig.general.unsafe-accounts-conf` was unset.
This commit also updated documentation throughout the aerc modules to
be in line with this change, and fixed minor typos/formatting therein.

* aerc: make assertion plaintext and add test case
This commit adds a test case to check both the warning on unset
`unsafe-accounts-conf = true` when aerc accounts are configured
with Nix, and the new assertion when per-account configuration
contains unsupported subsections (i.e. general).
It also fixes minor formatting issues and typos.
