* Fix examples/config-sample.json to match the current config format
The sample config has not been valid since the 2023 disk layout rework
and currently fails to parse, so the file the README points users at
cannot be used:
- sector_size was null, but SectorSize became a required object
- partitions were missing the dev_path key, which the parser reads
- the /home size used the Percent unit, which no longer exists
- /home started at 20 GiB while / ended at 20993 MiB, overlapping it
- gfx_driver kept the old "All open-source (default)" value
Sizes and keys now mirror what the installer itself writes when saving
a configuration.
* Cover the example configs with a parsing test
Nothing in the test suite or CI reads examples/, which is how the sample
config could stay broken for years while every other config surface kept
working. Parse both example files through ArchConfigHandler, and check
the partition entries directly since the parser only reaches them when
the configured device exists on the machine, which is never true in CI.
* Fail the partition test when the example config has none
The loops in test_example_config_partitions would not execute if
device_modifications or a device's partitions were empty, so the test
could pass while checking nothing.
