- SizeParser: wrap TB-suffix overflow in try/catch so callers get
ArgumentException with the parameter name rather than OverflowException.
- New-PveVm/New-PveContainer: validate -DiskSize/-RootFsSize before
ShouldProcess so typos like "512M" are rejected even with -WhatIf and
even when the matching -DiskStorage/-RootFsStorage is omitted.
- Add Pester tests for the new DiskSize and RootFsSize validation paths,
including a new New-PveContainer.Tests.ps1.
- Add SizeParserTests coverage for the TB overflow path.
