Maurice 62978aab5a Move five more domains onto the plugin RPC decorators
categories, weather, rates, todos and daynotes: 11 more methods, taking the
registry to 15 of 113. Handler bodies and messages are verbatim; the ledger test
tracks the split.

Two things the move surfaced rather than introduced. PluginGuards could not stay
in PluginsModule: that module imports 22 domain modules, so a domain importing it
back for the guards would close a hard cycle and the only way out would be
forwardRef. It now lives in a PluginGuardsModule leaf that imports nothing which
leads back, the same shape MailerModule got for AuthModule.

And the todo and daynote writes broadcast. Those events are not decoration, they
are what keeps an open session from showing stale data after a plugin write, so
they came across from the deps factory with the handlers, and there is a test
that a failed write broadcasts nothing.

Worth knowing for the next domains: todos are edited under 'packing_edit', not
under a todo-specific action, and TODO-RPC-003 pins that. Each new class also
asserts it is actually listed in its module providers, since a decorated class
nobody registers is invisible to discovery and answers PERMISSION_DENIED with no
other symptom.

/**
* The coverage ledger: the anchor for the whole decorator rollout.
*
* Every wire method is owned exactly once, either by the legacy router blocks in
* rpc-host.ts or by a decorated *.rpc.ts class in the registry. Both sets are derived
* by construction, so no list is maintained by hand and the test cannot drift.
*
* It fails the moment a migration PR moves a method and forgets to delete the legacy
* registration, deletes one without adding it, or forgets to list a new *.rpc.ts class
* in allRpcControllers().
