[pve-devel] [PATCH installer] tui: switch to `f64` for disk sizes

previously the tui used `u64` internally to represent the disk size.
since the perl-based installer expects GiB as floats and that is also
what is displayed in the tui that meant a lot of converting back and
forth. it also lead to an error where the disk sizes that were set
seemed to not have been persisted, even though the sizes were
correctly set. this commit refactors the installer to convert the size
once in the beginning and then stick to `f64`.
