chore(shopfloor): register fp_rpc.js asset + bump to 19.0.30.2.0 (P6.3.6)

Adds the Phase 6.3 fpRpc wrapper to the web.assets_backend bundle.
Placed before its consumers so the `import { fpRpc } from "./services/fp_rpc"`
calls in job_workspace, shopfloor_landing, manager_dashboard, and
hold_composer resolve.

+## Shop-floor action endpoints — credit the correct tech via `tablet_tech_id`
+The tablet sits on a long-lived "shopfloor service" Odoo session shared by many techs. The actual tech-of-record is established via the PIN unlock (Phase 6); their id lives in the OWL `fp_shopfloor_tech_store` service and is sent as `tablet_tech_id` on every action RPC.
+
+When writing a NEW shop-floor controller endpoint that **writes** (creates a record, calls a `button_*` method, posts to chatter):
+1. Add `tablet_tech_id=None` as a kwarg on the route handler.
+2. At the top, call: `env = env_for_tablet_tech(request.env, tablet_tech_id)` (from `fusion_plating_shopfloor/controllers/_tablet_audit.py`).
+3. Use `env` (not `request.env`) for all subsequent writes. `env.with_user(...)` is applied internally so `create_uid` / `write_uid` / chatter authorship carry the right uid.
+4. Read-only endpoints (load / kanban / funnel / overview) don't need this — leave them as `request.env`.
+
+On the client side: use `fpRpc()` from `services/fp_rpc.js` (drop-in for `rpc()`) for action calls. It auto-injects `tablet_tech_id`. Read calls can keep using plain `rpc()`.
+
+If `tablet_tech_id` is missing or invalid, `env_for_tablet_tech` falls back to the session uid — old callers and pre-Phase-6.3 endpoints continue working.
+
 ## Removing menus/records — Odoo does NOT auto-delete orphans
 Deleting a `<menuitem>` (or any `<record>`) from a data XML file does NOT remove the corresponding database row. The XML loader only updates records it sees; orphans persist in `ir.ui.menu` / `ir.model.data` until you delete them explicitly. Symptom: the menu still appears in the UI after `-u`. Fix — add a `<delete>` directive in a data file with `noupdate="0"`:
 ```xml
