refactor: unify call-ref and tests rendering format between audit and inspect commands

[carlos-alm]

Summary

BEHAVIOR CHANGE: codegraph audit's Calls/Called by/Tests sections now match inspect.ts's richer format (same pattern as #1756's impact-level unification earlier in this batch).

• audit.ts's renderCallRefs/renderRelatedTests and inspect.ts's renderExplainEdges (calls/called-by/tests portions) duplicated near-identical rendering with different formats: audit.ts's had no indent support, no "no edges" fallback, and unpluralized "Tests (N):"; inspect.ts's had all three.
• Investigated downstream dependencies first: only one existing test exercises renderExplainEdges's text output and asserts on a format that didn't change; audit.test.ts only tests the data layer; codegraph query/context use entirely different renderers, untouched.
• Extracted shared renderCallRefsSection/renderNoCallEdgesFallback/renderRelatedTestsSection into a new src/presentation/call-ref-sections.ts (following the impact-levels.ts pattern/location from Duplicate impact-level rendering logic: presentation/audit.ts vs presentation/queries-cli/impact.ts #1756), adopted in both call sites.

Closes #1772

Test plan

• npm test — full suite green (3560 passed, 0 failed), zero test updates needed
• npm run lint / npx tsc --noEmit — clean
• Manual verification against this repo's own graph: no-edges case now shows the fallback message in audit (previously silent); populated case now byte-identical between audit/inspect; pluralization verified both ways (Tests (1 file): vs Tests (58 files):)

Stacked on #1898 (base branch fix/issue-1771-dispatch-table-reference-edges) — only the presentation diff is this issue's change.

Greptile Summary

This PR extracts duplicated rendering helpers for "Calls", "Called by", and "Tests" sections from both audit.ts and inspect.ts into a new shared module src/presentation/call-ref-sections.ts, following the same pattern established by the impact-levels.ts extraction in #1756.

• The three new exported functions (renderCallRefsSection, renderNoCallEdgesFallback, renderRelatedTestsSection) centralise formatting logic and add two behaviour improvements to codegraph audit: a "no call edges" fallback message now shows when both callers and callees are empty, and the Tests label is now correctly pluralised (Tests (1 file): vs Tests (N files):).
• Both call sites pass TypeScript's type checker via structural compatibility between the new CallRefLike/RelatedTestRefLike interfaces and the underlying domain types.

Confidence Score: 5/5

Safe to merge — purely a presentation-layer refactor with no logic changes beyond the two intentionally documented behaviour improvements in audit.

All three changed files are in the presentation layer and touch only console output. The extracted helpers are structurally identical to the inline code they replace; the two behaviour additions (no-edges fallback and pluralised Tests label in audit) match what inspect already produced and are explicitly called out in the PR description. TypeScript compatibility is enforced by the structural interfaces, and the full test suite passes with zero test updates.

No files require special attention.

Important Files Changed

Filename	Overview
src/presentation/call-ref-sections.ts	New shared module — well-documented, correct interface definitions, sensible defaults for indent, and all three helpers guard against empty input before printing.
src/presentation/audit.ts	Removes local renderCallRefs/renderRelatedTests and adopts the shared helpers; kindIcon import retained (still used in renderFunctionHeader); behaviour changes are intentional and documented.
src/presentation/queries-cli/inspect.ts	Inline rendering loop in renderExplainEdges replaced by four shared-helper calls; formatting and fallback behaviour preserved exactly.
