Paladium Bot v100.3.40 - Test Report

- Uploader caption input now proceeds directly to the next stage/preview without a separate caption confirmation.
- Uploader schema migrations/checks are marker-gated instead of running DDL/schema inspection on every webhook.
- Chat-sync schema initialization is marker-gated instead of running CREATE/INSERT work on every webhook.
- Bot-generated Telegram pin service updates are detected early and the exact service message is deleted from its destination after the webhook response.
- Human-admin pin service notifications are not targeted by the cleanup path.

Validation:
- PHP syntax: PASS (74 files)
- ZIP integrity: PASS after packaging
- Live Telegram production test: NOT RUN in this environment
