docs: update browser summary report documentation and docstrings

[uriahf]

FOCUSED DOCUMENTATION TASK — UPDATE PYTHON SUMMARY REPORT DOCUMENTATION

Summary of Changes:

1. user_guide/06-summary-reports.qmd:

   • Documented current static browser report produced by create_summary_report(..., renderer="browser") with six top-level sections in exact order: Prevalence, Prediction Distribution, Calibration, Discrimination, Utility, Performance Table.
   • Clarified that the Summary Report browser backend produces a single offline, self-contained HTML file with embedded renderer JS/CSS, without claiming this for all standalone components.
   • Replaced hard-coded rtichoke_viz v0.5.0 with version-neutral wording referencing the vendored immutable rtichoke_viz renderer.
   • Added create_summary_report_times() section describing its five top-level sections (Event Probability, Calibration, Discrimination, Utility, Performance Table) and intentional omissions (no Prevalence, no Prediction Distribution, no AUROC summary metric).

2. Public Docstrings (src/rtichoke/summary_report/summary_report.py & src/rtichoke/probs_distribution.py):

   • Updated create_summary_report() docstring to describe the 6 top-level static report sections.
   • Updated create_probs_histogram() docstring to replace risk percentile rank distributions and PPCR / Risk Percentile with neutral prediction percentile rank distributions and PPCR terminology.

3. Obsolete Statements Removed:

   • rtichoke_viz v0.5.0 hard-coded version tag.
   • Claims that static summary report contains only Performance Table + ROC + calibration.
   • Claims that generated Summary Report HTML requires sibling JS/CSS files.
   • Risk Percentile terminology in public docstrings and guide.

4. Preserved Scope Boundaries:

   • Zero runtime, statistical, schema, ID, or public API signature changes.
   • Preserved internal statistical identifiers such as _event_risk_summary_metrics_spec, event_risk, event-risk, and competing_heuristic.

Verification Results:

• uv run pytest: 389 passed, 12 skipped.
• Code review rating: #Correct#.
