leonarski_f 9e57219b31 common: add azimuthal-angle (phi) sectors to ROIAzimuthal
ROIAzimuthal can now be restricted to an azimuthal-angle sector in
addition to its Q/d range, enabling STXM-style directional ROIs. phi
bounds are optional (both-or-neither); absent means a full 360 ring, so
existing Q-only azimuthal ROIs are unchanged.

- ROIElement::CheckROI gains a phi_deg argument; box/circle ignore it.
- MarkROI gains an optional phi_map; ROIMap builds it from Phi_rad
  alongside the resolution map only when azimuthal ROIs are present.
- phi bounds are normalized to [0,360) and wrap-around sectors are
  supported (phi_min > phi_max).
- ROIConfigAzim carries phi_min/phi_max (kept trivially copyable for the
  union; phi_min == phi_max means full ring).

No phi crosses the wire yet (CBOR/API wiring follows separately).
