fix: merge version ranges when adding existing package signer (#3125)

* fix: merge version ranges when adding existing package signer

   Previously, add_package_signer unconditionally inserted the new
   version range, overwriting any existing authorization for that signer.
   Now it OR-merges the new range with the existing one, so running
   signer add multiple times accumulates permissions rather than
   replacing them.

* add --merge flag to registry package signer add

  Default behavior remains overwrite. When --merge is passed, the new
  version range is OR-merged with the existing one, allowing admins to
  accumulate permissions incrementally.

* add missing attribute to TS type

* make merge optional

* upsert instead of insert

* VersionRange::None on upsert
