fix: surface silent failures in SL, wiki, and embedding wiring

- require non-empty `vertex.location` in the project schema instead of defaulting
  to an empty string with a description that promised SDK fallback the resolver
  never honored
- log YAML parse failures from `SemanticLayerService.loadSource` and
  `KnowledgeWikiService.readPage` so corrupted overlays aren't silently treated
  as "does not exist" by ingest/agent tools
- push directory-listing errors in `loadAllSources` and `listPageKeys` into the
  load-error / log path instead of returning empty success
- accept an `embeddingProvider` in `createLocalProjectMemoryIngest` and plumb the
  resolved CLI provider through `mcp-server-factory`; warn in both the memory
  and bundle runtimes when they fall back to `NoopEmbeddingPort` while the
  project config requests an active embedding backend
- clarify `embeddings.dimensions` description as a placeholder valid only with
  `backend: none`, and tighten the sentence-transformers `base_url` description
  to call out that managed-daemon resolution is CLI-only
