chore(core): return N4W1 in Features.capabilities

[romanz]

Will be used to detect N4W1-enabled builds.

$ trezorctl -j get-features | jq .capabilities | grep N4W1
  "N4W1"

Walkthrough

This change introduces a new device capability identifier N4W1 assigned to enum value 25. The capability is added to the protobuf definition in messages-management.proto and propagated to corresponding Python enum files in both core and client libraries. The get_features() function in base.py is modified to conditionally include this capability in the advertised features list when utils.USE_N4W1 evaluates to true.

Check name	Status	Explanation	Resolution
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	Write docstrings for the functions missing them to satisfy the coverage threshold.
Description check	❓ Inconclusive	The description is minimal and vague, lacking structured sections required by the repository template (development status, project assignment, QA notes).	Add structured sections following the template: development status, project assignment details, and QA testing instructions or mark as 'no-QA' if testing is not required.

In `@core/src/apps/base.py`:
- Around line 165-167: get_features() currently appends Capability.N4W1 when
utils.USE_N4W1 is true, but this can advertise N4W1 in universal builds; change
the guard so Capability.N4W1 is only appended when both utils.USE_N4W1 and the
bitcoin-only build flag are true (e.g., check utils.BITCOIN_ONLY or equivalent
build flag alongside utils.USE_N4W1) where the append to f.capabilities (the
f.capabilities.append(Capability.N4W1) call) occurs.
