Fix Printify uploads limit, weclapp comment visibility, Odoo call_method hints - #1311

Summary

Three catalog tools fail on Cloud because their schema or description leads the model to a request the API rejects. Errors are from the last 14 days.

• printify_list_uploads: the description said up to 100 images per page. Printify answers limit: The limit may not be greater than 50 (code 8150). 21 of 21 calls with limit=100 failed, and all calls at 50 or less succeeded. Now says 1-50, with minimum: 1 and maximum: 50.
• weclapp_add_comment: privateComment and publicComment both defaulted to false, and weclapp answers "comments have to be either private or public". The 5 errors are exactly the calls that left both false; every success set exactly one. The defaults are gone, and the tool and both flags now say to set exactly one of them.
• odoo_call_method: 28 errors "missing a required argument: 'vals' / 'vals_list' / 'domain' / 'field_name'", because the model sent the values as loose fields. The kwargs description now says required arguments go under their Odoo parameter name ({"vals": {...}} for write, {"vals_list": [{...}]} for create, {"domain": [...]} for search), and points to odoo_create / odoo_write. The ids description now says to call once per id when a method fails with "Expected singleton".

Changes

• intl/printify.json, de/weclapp.json, intl/odoo.json: descriptions and schema as above. No tool, path or body mapping changes.
• Static assertions in the three .live.spec.ts files.

Type

• Bug fix

Testing

• Added/updated unit tests

Commands, run from the repo root unless noted:

• node scripts/validate-adapters.mjs --warn: 574 passed, 0 failed, 1442 warnings (same count as main; none new).
• node scripts/regenerate-catalog.mjs: no diff.
• node scripts/adapter-count.mjs --check: OK, 560 adapters.
• node scripts/generate-llms-txt.mjs --check: up to date.
• In packages/backend: npx jest src/adapters/intl/printify src/adapters/de/weclapp src/adapters/intl/odoo.live → 5 suites, 58 passed, 3 skipped (live). npx jest src/adapters/catalog → 10,658 passed.

Same behaviour in Cloud and self-hosted. Installed connectors pick the change up through the catalog re-sync.
