fix(inbound-api): API-method recompile/invalidate reaches the peer central node; stale doc; locked-override name rule (ScadaBridge#103)
(a) Inbound API compile state (#75) is per central node: a recompile cleared the known-bad record only on the node that answered, and the peer kept refusing the unchanged script with SCRIPT_COMPILE_FAILED (the per-request revision check only notices a changed script). Create / update / delete (ManagementActor post-commit), RecompileApiMethod, and API methods written by a Transport bundle import now publish InboundApiMethodInvalidated on the central cache-invalidation topic (#100 item 3). The new InboundApiCacheInvalidationHandler drops that method's compiled handler, known-bad record and cached ApiMethod row on the peer, which compiles the current text on its next request. (b) docs/components/InboundAPI.md no longer claims a direct DB edit stays stale until restart: the per-request revision check picks it up once the node's cached row expires (ApiMethodCacheTtl, 5 s). Component-InboundAPI, Component-Host and the #85 cache audit describe the peer invalidation. (c) Decision: the import's locked-override warnings keep EXACT (ordinal) name matching, because FlatteningService matches override names ordinally. An override differing from a locked member only by case never reaches that member's lock check (the flattener drops it as unresolved), so a "targets a LOCKED member" warning for it would be false. The comparer is now named (LockedOverrideNameComparer) and documented, and pinned by tests on both sides (flattener + import). Tests: the peer's known-bad record is cleared by a recompile (and validate leaves it alone); create/update/delete and the import publish the invalidation; the handler drops only the named method; composition root registers the handler; case-only override gets no lock warning; the flattener matches override names exactly.
