Add SEO descriptions to API reference and event catalog

[mintlify]

Summary

Adds missing description frontmatter to 243 documentation pages so they appear well in search results and Mintlify navigation snippets.

Changes

• 51 timeseries API reference pages (api-reference/data/timeseries/*.mdx): Each now describes the specific timeseries metric retrieved by the endpoint (e.g. heart rate, glucose, blood pressure).
• 192 event catalog pages (event-catalog/*.mdx): Each webhook event page now has a description summarizing when the event fires and what data it relates to. Covers daily.data.*.created, daily.data.*.updated, historical.data.*.created, plus lab test, provider connection, and continuous query events.

SEO criteria applied

• All descriptions are between 50 and 160 characters.
• No titles exceed 60 characters.
• Descriptions summarize page content in plain language without changing any page body content.

Skipped

The 11 files in snippets/ were intentionally not modified — they are reusable content fragments imported into other pages, not standalone navigation pages, so SEO frontmatter does not apply to them.

Validation

• mint validate passes
• mint broken-links passes
