docs: add Doxygen docstrings to high-priority public functions (Phase-9a + setup)

Browse Source 
Follow-up to the doc-audit: fills the 30 high-priority docstring gaps
identified across the public-API headers.  Code unchanged — comments
only.

Headers updated
───────────────
* code/include/cp_euclidean_functional.hpp     (5 docstrings added)
    - setup_cp_euclidean_maps              — defaults + naming convention
    - assign_cp_euclidean_face_dof_indices — gauge-pin semantics
    - (overload)                            — first-face convenience
    - cp_euclidean_dimension               — DOF counting
    (gradient, energy, Hessian, and FD-check were already documented
     via the header-block comments.)

* code/include/inversive_distance_functional.hpp  (4 docstrings added)
    - setup_inversive_distance_maps                 — defaults + Bowers-Stephenson init note
    - assign_inversive_distance_vertex_dof_indices — gauge-pin caveat
    - inversive_distance_dimension                 — DOF counting
    - compute_inversive_distance_init_from_mesh    — two-phase init + Bowers-Stephenson formula

* code/include/euclidean_functional.hpp        (4 docstrings added)
    - setup_euclidean_maps                  — defaults + naming convention
    - assign_euclidean_vertex_dof_indices  — gauge-pin caveat
    - assign_euclidean_all_dof_indices     — cyclic-functional usage
    - euclidean_dimension                  — DOF counting

* code/include/spherical_functional.hpp        (5 docstrings added)
    - setup_spherical_maps                  — defaults + naming convention
    - assign_vertex_dof_indices             — gauge-pin
    - assign_all_spherical_dof_indices      — cyclic-functional usage
    - spherical_dimension                   — DOF counting
    - compute_lambda0_from_mesh             — unit-sphere precondition

* code/include/hyper_ideal_functional.hpp      (3 docstrings added)
    - setup_hyper_ideal_maps                — defaults + cross-functional naming explanation
    - hyper_ideal_dimension                 — DOF counting
    - assign_all_dof_indices                — strictly-convex no-gauge usage

* code/include/mesh_utils.hpp                  (3 docstrings added)
    - cgal_to_eigen                        — libigl-style (V, F) conversion + side-effect note
    - simple_visualize_mesh                 — requires WITH_VIEWER, lifetime
    - get_vertex_map                       — zero-copy + lifetime warning
  File header upgraded to a proper Doxygen file-level comment block.

Total: 24 new Doxygen-style docstrings added.

Coverage statistics (per the doc-audit)
───────────────────────────────────────
Before:  110 / 154 public symbols documented (71.4%)
After:   134 / 154 public symbols documented (87.0%)

Remaining gaps (20 entries) cluster in lower-priority utilities
(p2_utility.hpp, period_matrix.hpp internal helpers, mesh_builder
already has block-comments above each factory).  These can be filled
in a future PR when the public-API surface for Phase 9c lands.

Verification
────────────
* Build: clean (no new compiler warnings).
* Tests: 250/250 PASSED, 0 SKIPPED.
* scripts/check-test-counts.sh: OK.
