docs: add CLI option to rotating API keys tutorial

[mintlify]

Restructures the "Rotate a key" section in the Rotating API keys tutorial into a <Tabs> block with three options: Web UI, CLI, and API.

• Adds a new CLI tab covering kosli rotate api-key, including single-key, multi-key, and JSON-output (jq) capture variants, with a link to the command reference.
• Preserves the existing Web UI steps and API/curl examples as separate tabs.
• No content removed; only restructured for parity across interfaces.

Review of PR #289

• Read changed file and CLAUDE.md
• Check for relative links, navigation updates, front matter
• Review content quality and structure
• Post findings

Findings — tutorials/rotating_api_keys.mdx

No critical issues found. The restructuring is clean and the prior review suggestions about --grace-period-hours consistency have already been addressed (commit ff444e5).

Suggestion — The JSON-output example (line 65) omits --grace-period-hours like the multi-key example, but unlike those two, it doesn't mention this omission in its lead-in text. Consider adding a brief note or including the flag for completeness, so readers don't wonder whether --output json changes the default behavior.

Summary

Check	Status
Front matter (title, description)	Pass
Navigation entry in config/navigation.json	Present (line 118)
No relative links	Pass — all links are root-relative
Internal link targets exist	Pass — /client_reference/kosli_rotate_api-key resolves to kosli_rotate_api-key.md
Writing style (active voice, American spelling, "Kosli" branding)	Pass
Tabs structure	Clean — Web UI / CLI / API provide good parity

Looks good to merge. The only remaining nit is the grace-period omission note on the JSON-output example, which is minor.
