docs: add configuration guide (wiki + docs/CONFIGURATION.md)

[igoroctaviano]

Summary

• Adds a single-page configuration guide at docs/CONFIGURATION.md covering the topics requested in Create documentation page in the wiki #207 (and the related Configurable servers #5 follow-up for documenting configurable servers / the header server-selection button).
• Links the guide from the README and summarizes remaining config topics in a table.
• Mirrors the same page on the GitHub wiki (Home + Configuration).

Topics documented

• External DICOMweb server configuration
• Runtime server selection via enableServerSelection (header API / “link” icon)
• Secondary GCP annotation store via the gcp query parameter
• Per-finding annotation colors (annotations[].style) and note on selection highlight
• Read-only mode (disableAnnotationTools) and disabling the worklist (disableWorklist)
• Local Orthanc / CORS troubleshooting (addresses the setup confusion raised in Create documentation page in the wiki #207)

Related issues

• Closes Create documentation page in the wiki #207
• Closes Configurable servers #5 (feature is implemented; this supplies the remaining documentation called out in the issue comments)
• Related: Support fetching of all data from both primary and secondary DICOM store in the URL #320 (secondary store enhancement; documented current gcp behavior only)

Test plan

• Review docs/CONFIGURATION.md for accuracy against src/AppConfig.d.ts and public/config/*.js
• Confirm README links resolve
• Confirm wiki Configuration page matches the repo doc after wiki push
• Spot-check that enableServerSelection: true still shows the header server button as described

Follow-up commit after reviewing the guide against Slim and dicom-microscopy-viewer (0.48.22):

Corrections

• gcpBaseUrl does not affect path-only server selection or ?gcp= (only GCP path-based default-server rewrite)
• Custom runtime server is write: false and collapses SOP-class client mapping (including ?gcp= split) until default is restored
• Documented slim_server_selection_mode persistence
• Split SR ROI vs bulk ANN style models (dmv setROIStyle vs setAnnotationGroupStyle)
• Clarified yellow default vs palette fallback, selection vs dmv ANN highlight colors
• Noted dmv ANN bulkdata fetch via SM client when using secondary gcp
• disableAnnotationTools also hides bundled toolbar controls (e.g. Go to); disableWorklist does not remove deep-link routes
