Update doc: split RUNMODEM.md, clarify USRP-specific workarounds

This reworks the documentation:
- split up RUNMODEM.md into separate documents for gNB, UE, NTN
- explains USRP workaround and patches
- makes a standalone UE doc file that explains UE-specific configuration
  & modes
- better explains physical simulators
- adds a document on tracy
- cleanup

CI: fix Aerial conf for test with 30 MHz BW

More compilation improvements

Mostly to decouple NR files from LTE headers.

At least in one instance, ulsch_input_buffer_array, using an LTE constant in
NR code was quite dangerous because the buffer in NR could easily be larger
than what the LTE constant foresee.

UE: Fix CSI RS Measurement

1. Fix regression introduced in !3834.
2. ZMQ has no interference or artificial noise so the interference plus noise
   measured is always 0. nr_csi_rs_pmi_estimation() returns SINR as 0 if noise
   is 0 which reports CQI as 0. This fix computes SINR if noise is 0 instead of
   returning.

UE: Implement SUCI Profile Scheme A

This MR modifies the nrUE to support Profile Scheme A based SUCI generation as
outlined in TS 33.501 §C.3 Elliptic Curve Integrated Encryption Scheme (ECIES),
this further extends SUCI generation, which currently only supports the NULL
Scheme.

Changes:
- Extend UICC structure for SUCI parameters.
- Add cryptographic primitives (Curve25519, X9.63 KDF).
- Add an abstracted function to transfer digit strings into their corresponding
  BCD value.
- Updates SUCI generation to support Profile Scheme A.
- Updates NAS SUCI encoding to support hexadecimal cryptographic output in
  addition to BCD encoded MSINs.

Notes:
When a configuration file specifies an unsupported Profile Scheme, the NAS layer
triggers a fatal error. This occurs either because Profile Scheme B is
unimplemented or the build uses OpenSSL < 3.0, which lacks Curve25519 and X9.63
KDF support, ensuring users are informed of the incompatibility. Support for
Profile Scheme B (TS 33.501 §C.3.4.2 Profile B) can be implemented at a later
stage using P-256-based encryption.

The implementation of SUCI Profile Scheme A was tested against Open5GS’s core
implementation. OpenAirInterface’s cn5G does not yet support Scheme A and should
be extended to include it in a future update.

This allows to compile physical simulators by compiling only tests with
"ninja tests". It fixes a regression.

Merge remote-tracking branch 'origin/hotfix_layer_mapping_aarch64' into integration_2026_w14 (!4021)

hotfix for 4 layer mapping on aarch64

This hotfix fixes a small bug appearing on aarch64 in the 4-layer PDSCH mapping
function. It was an error in the original implemntation.

Extend UICC configuration parsing to provide: routing_indicator,
protection_scheme, home_network_public_key, and home_network_public_key_id.
Use the protection_scheme value to decide what SUCI Profile Scheme to
apply during SUCI generation. Add support for Profile Scheme A which
provides ECIES-based encryption using Curve25519 and X9.63 KDF as outlined
in TS 33.501 Section C.3.4.1 Profile A.

When a configuration file specifies an unsupported Profile Scheme,
the NAS layer triggers a fatal error. This occurs either because
Profile Scheme B is unimplemented or the build uses OpenSSL < 3.0,
which lacks Curve25519 and X9.63 KDF support, ensuring users are
informed of the incompatibility.

Save space in the main tutorial, and group UE-specific configuration in
one page. Add a reference where to find UE-related configuration
information.

I only modify the headings and write an introductory sentence, but the
content is otherwise unmodified.

Split out to make a standalone NTN configuratio page that would be
easier to find. I only modify the headings in the new file and write an
introductory sentence of the tutorial, the rest is unchanged.

Change OAI license to CSSL v1.0

Adjust target SNR values and introduce RSSI thresholds in the VNF configuration
files to prevent UL saturation. These changes improve uplink stability and
performance for tests with Aerial and WNC RU.

Fix Delta MCS mode, reimplement UL power control

This change set fixes the "delta-MCS" mode, and reimplements the UL power
control loops at gNB, i.e., for PUSCH and PUCCH. It further adds new T traces
to log PUSCH/PUCCH power infrmation, and cleans up code.

The "delta-MCS" mode in OAI refers to configuring a UE with deltaMCS in the
PUSCH-PowerControl IE (see TS 38.331). In this mode, the UE adjusts the PUSCH
power for transmissions to take into account for MCS (see TS 38.213 Sec. 7.1).
In other words, the target SNR can be set to a somewhat low value, and the UE
will still use the right power for UL transmissions. Note that the spec only
foresees this adjustment of UL power when using one layer. In contrast, in the
"normal" mode, the gNB sends TPC commands to keep a UE at a fixed target SNR
(default: 20dB), regardless of the MCS or number of layers. Future work is
planned to completely remove this fixed target SNR, which is not done in this
MR yet.

Further, there is a new power control loop implementation. Prior to this MR, on
each UL transmissions, the gNB uses the SNR to decide about TPC sent to a UE in
the next transmissions. The new implementation relies on averaging the SNR, and
a "TPC in flight" average to account for the slow reaction of the average SNR.
The sum of both quantities is the current SNR that is used by the UE. See the
commit messages or documentation for more information.

Further cleanup to group data (e.g., power control configuration, refactoring of
code to save space, ...) is done. Two new T traces GNB_MAC_PUSCH_POWER_CONTROL
and GNB_MAC_PUCCH_POWER_CONTROL are added; documentation exists to explain how
to graphically plot corresponding graphs.

Configure DigitalBeamTable in OAI and pass down to Aerial L1

With this MR it will be possible to define a Beamtable in OAI and pass it down
to a L1 (Aerial or OAI) which then will either use them locally to apply
static beamforming (Split 8 with USRP) or pass them down to the RU using 7.2
split with Section Extension 1.
