Merge remote-tracking branch 'origin/NTN_FR2_bands' into integration_2026_w11 (!3414)

Browse Source 
Added NTN-FR2 FDD bands defined in release 18 in Ka-band range

* NTN-FR2 bands 510, 511, 512 added. TS 38.101-5 v 18.9 defines these 3 FR2-FDD
  bands for NTN operation.
* These bands are defined in Ka band range (17.3Ghz - 31Ghz).
* Tested using the added conf files using RFSIM and GEO configuration.
* There were some inconsistencies observed when testing with RFSimulator before UE
  Syncs to the gNB in terms of samples being written for FR2 configurations. Once
  the UE syncs, the inconsistencies disappear.
* this is the problem - UE writes incorrect number of samples and gNB complains
  about getting samples in past
* The above inconsistencies were also fixed in this merge request.
* These commits solving above inconsistencies were removed from this MR and a
  different MR was raised. MR with those commits: !3928.
