feat(bling): add proposal (orçamento) tools

[palandri]

Add 6 new MCP tools for commercial proposals (propostas comerciais): list, get, create, update, delete, update_status.

[rapguit]

Thanks for the contribution, and welcome — first PR here.

The 6 proposal tools themselves look solid: tool shapes are consistent with the rest of the Bling surface, REST paths against /propostas-comerciais/... match the API, and expandContact is gated + fails per-contact so a missing/blocked lookup doesn't take the whole list down.

Three things to clean up before this can land:

1. MANAGED_TIER_HINT is removed in packages/erp/bling/src/index.ts. The instructions: MANAGED_TIER_HINT argument on new Server(...) is the standard pattern every server in this catalog ships (~115 servers). It's likely a side-effect of an older base branch (the hint was added after you forked); please restore the constant + the instructions: MANAGED_TIER_HINT argument so this server stays consistent with the rest.

2. package-lock.json drift: the lockfile change is +433/-99 and includes version bumps + new workspace links for ~12 packages that aren't part of this feature (e.g. @codespar/mcp-btg, mcp-coinbase-cdp, mcp-paypal, mcp-iniciador, etc). That's from running npm install on a stale base. A clean rebase on current main + npm install should reduce the lockfile diff to just whatever the proposal feature actually needs.

3. @types/express added at root devDependencies without a corresponding consumer — Bling's index.ts doesn't import Express. If it's unintentional, please drop the entry; if it's preparation for a follow-up, happy to hear the context.

Once those are addressed I'll re-review and merge. Thanks again!

Formalizing as a changes-requested review for visibility — the three points from my earlier comment (#180 (comment)) still stand:

1. Restore MANAGED_TIER_HINT (regression).
2. Rebase on main + clean npm install to drop the unrelated lockfile drift.
3. Drop the orphan @types/express devDep (or justify it).

Re-request review once those land. Thanks!

Thanks for the proposal (orçamento) tools, @palandri — clean tool shapes and solid coverage. I went ahead and applied the three requested changes to get this landed: restored the MANAGED_TIER_HINT, rebased on main for a clean lockfile (dropped the unrelated drift), and removed the orphan @types/express devDep — plus bumped the tool-count test to 34. CI is green across build/test, catalog audit, and secret scan. 🚀

I'm really sorry for the lack of response on this @rapguit. I've been dealing with some health issues recently, which kept me from addressing your requested changes. Thank you so much for stepping in, picking this up, and getting it over the finish line. I really appreciate it!
