Weekly Cloudinary usage report and quota alerts in Slack

Every Monday at 8 AM, pull the current Cloudinary account usage using Cloudinary's Get Account Usage operation, format a plain-English weekly summary, and post it to a Slack ops channel using Slack Bot's Send a Message operation.

Cloudinary's /usage response reports each metric as an object with usage, limit, and used_percent. Read the plan name from the root of the response, then walk the storage, bandwidth, transformations, and credits objects. Format each metric as one line: `<label>: <usage> / <limit> (<used_percent>%)`. Show storage and bandwidth in a human-readable unit (MB or GB) when the API returns raw byte counts, but keep the percent exactly as Cloudinary reports it. Prefix any line whose used_percent is above 80 with a ⚠️ warning emoji so anything close to the plan ceiling stands out immediately.

The message header should include the plan name and the report date, followed by each metric line, so the whole digest is scannable in one glance. This is deterministic: fetch, format, post. There is no summarization or judgement, so build it as a code workflow. The Slack channel to post into should be a configurable parameter (default to an ops channel such as #ops-alerts).
