Linux/macOS: fix hidden volume FAT size limit

Browse Source 
The Unix volume creation wizard applied the FAT32 sector-count limit as a blanket check for device-hosted hidden-volume outer volumes. On 512e disks Linux reports 512-byte logical sectors, so this incorrectly rejected larger device-hosted outer volumes even when the selected outer filesystem was not FAT.

Compute the actual VeraCrypt filesystem/data area size through a shared helper and apply the FAT32 size limit only when FAT is selected. This preserves correct FAT validation while allowing non-FAT outer volumes to proceed to the existing hidden-volume size estimation flow.

Update text-mode creation so FAT is not offered when the selected size cannot support it, and default to the platform native filesystem in that case. Clarify the user-facing FAT limit wording to refer to logical sector size.

Fixes #262
