[AZ-485] [AZ-486] Cycle 1 docs refresh (Step 13)

Phase B cycle 1 was a structural refactor only: F4 (barrel imports +
STC-ARCH-01) and F7 (endpoint builders + STC-ARCH-02). This commit
brings docs in line with source after the cycle, no code changes.

Module docs (12 consumers): swap every /api/<service>/... literal in
code snippets and integration tables for the matching endpoints.*
builder; note the barrel import migration in Dependencies.

New module doc: src__api__endpoints.md (public surface, F4 barrel
re-export note, STC-ARCH-02 enforcement, contract-test reference).

Architecture compliance baseline: mark F4 + F7 CLOSED with commit
hashes (23746ec, 8a461a2).

01_api-transport component description: add endpoints.ts + barrel to
Internal Interfaces, close the F7 caveat, extend Module Inventory.

ripple_log_cycle1.md: Task Step 0.5 reverse-dep analysis records the
import-graph closure (no extra docs needed beyond the direct set).

Carry-over reports landed alongside the docs:
- test_run_report_phase_b_cycle1.md (Step 11 outcome)
- implementation_report_refactor_phase_b_cycle1.md (cycle summary)

State file: trimmed to the autodev <30-line target; Steps 14 + 15
recorded as SKIPPED with rationale (no security or perf surface
changed in this cycle); pointer moved to Step 16 (Deploy).
