fix: add missing getContentByUrl import to crawl endpoint

[joelrb]

Description

Problem
functions/api/crawl.ts calls getContentByUrl(env, targetUrl, crawler) on line 256 to look up cached content when ?force=true is not specified. However, getContentByUrl was missing from the import statement on line 2. At runtime this throws ReferenceError: getContentByUrl is not defined, breaking the entire "fetch from cache" code path. Every non-force crawl request crashes instead of returning cached content.

Fix Applied
Added getContentByUrl to the named import on line 2 of functions/api/crawl.ts.

Framework Change
No framework changes.

Additional Notes

This was introduced in the merged security fix #640. The getContentByUrl function was correctly added to the crawl endpoint's logic but was omitted from the import statement. This is a one-line fix that restores the "fetch from cache" code path in the crawl endpoint.
