Lite-manifest CLI consumers never load dynamicPackages.server — same class-registration gap as #3415

#3415 established the pattern: any process that bootstraps entity classes via the `server-bootstrap-lite` manifest registers only `@memberjunction/*` (`MJ: *`) subclasses. If that process then instantiates entity objects for non-`MJ:` namespaces (BizApps, BCSaaS, any Open App schema), ClassFactory falls back to bare `BaseEntity`: typed field getters are missing, and anything reading `record[fieldName]` gets `undefined`.

#3430 fixes the worst symptom (metadata-sync's silent pull corruption) by loading `dynamicPackages.server` from `mj.config.cjs` during provider init. The same gap exists in every other lite-manifest consumer — none of them load dynamic packages today; only the full `ServerBootstrap` does (`loadDynamicAppPackages`):

- **MJCLI** (beyond the sync commands)
- **CodeGenLib** (`runCodeGen.ts`)
- **MJCodeGenAPI**
- **MCPServer**
- **A2AServer**

## Ask

Audit each for code paths that instantiate non-`MJ:` entity objects (`GetEntityObject`, `RunView` with `ResultType: 'entity_object'`, property-style field reads). Where exposed, add the same loader — #3430's `loadDynamicServerPackages` in MetadataSync is the reference (mirrors ServerBootstrap's robustness contract: no-op when absent, per-package try/catch, `ERR_MODULE_NOT_FOUND` tolerated, warn-and-continue otherwise). Consider hoisting the loader into a shared home (e.g. alongside the lite manifest) rather than five copies.

Severity gradient: consumers that only *read and display* suffer wrong/empty values; consumers that *write or key on* field values can corrupt data the way #3415 did. Audit the writers first.

Refs: #3415 (root-cause analysis with receipts), #3430 (metadata-sync fix).

Start with #3430's loadDynamicServerPackages and the full ServerBootstrap loader, then inspect the lite-manifest consumers: MJCLI, runCodeGen.ts, MJCodeGenAPI, MCPServer, and A2AServer. Audit writer paths first and confirm that exposed non-MJ entity-object paths load dynamicPackages.server with the stated error handling, without changing consumers that do not need it.
