Drop hardcoded version defaults and the un-discoverable label mapuser/jvalesmena/old-target-builds

- Remove the hand-maintained _NT_TARGET_VERSION -> friendly-name map (latest/24H2/...)
  from Join-CsvReports.ps1, along with its "Release" column in the HTML and step-summary
  tables; those labels cannot be auto-discovered.
- Stop hardcoding a version in the helper defaults: Import-SampleExclusions' -NtTargetVersion
  now defaults to empty (treated as the latest, so no NT-scoped row applies), and
  Build-SingleSample's -NtTargetVersionCode has no hardcoded code (the resolved value is
  always passed in). Blank MaxNtTargetVersion now uses [int]::MaxValue so 'latest'/empty
  matches the newest version's exclusion set.
