O3-5698: Add visit summary sections REST endpoint and SPI label/toggleable defaults

[BlessedAmrita]

Summary

Adds GET /ws/rest/v1/patientdocuments/visitSummary/sections, which lists the registered visit summary sections so an admin UI can display, toggle, and reorder them. Returns the standard REST collection shape ({ "results": [...] }), one entry per section with sectionKey, label, enabled, order, and toggleable, sorted by effective order.

The endpoint reads the same @Autowired List<VisitSummarySection> the PDF renderer uses, so a downstream module's custom section appears automatically with no change here. Access is guarded by the core Get Global Properties privilege (section metadata is not sensitive; no new module privilege).

Two additive default methods on the VisitSummarySection SPI back this:

• getLabel() resolves the section's localized heading via the existing message-source mechanism, falling back to a humanized section key so downstream sections without message bundles still get a usable label.
• isToggleable() defaults to true, overridden to false on the three always-on sections (facility header, patient info, footer) so their toggle can be locked in the UI.

Missing heading keys for the facility header and footer sections were added to the en/fr/ar bundles (fr/ar mirror English as placeholders, matching the module's existing convention).

Tests

Module suite green (api 120, omod including 6 new controller tests + 4 new SPI tests). Covers: every registered section listed, sorted by order, GP overrides reflected, always-on sections non-toggleable, labels resolved from the message source, and 403 on logout.
