dhcp-done: Write status at startup

We want the initial status file to be available as soon as the service
starts, so we never produce an error about reading the file contents.

This has a side benefit that the DHCP processes don't need to write out
a status file until they have acquired lease information from the
server.

build: use allowed over enabled or not-disabled

Meson feature options are typically in a tri-state of enabled, disabled,
or auto. The enabled and disabled functions on an option (from
`get_option`) no longer return true for auto features. Instead, the
expectation is to use `allowed()` which is true for both enabled and
auto.

Switch all uses of `enabled` to `allowed`.
Switch all uses of `not disabled` to `allowed`.

clang-format: re-format for clang-18

clang-format-18 isn't compatible with the clang-format-17 output, so we
need to reformat the code with the latest version. The way clang-18
handles lambda formatting also changed, so we have made changes to the
organization default style format to better handle lambda formatting.

See I5e08687e696dd240402a2780158664b7113def0e for updated style.
See Iea0776aaa7edd483fa395e23de25ebf5a6288f71 for clang-18 enablement.
