fix(cli): handle 413 payload-too-large errors for SBOM scans

[facundo-herodevs]

Closes https://github.com/neverendingsupport/data-and-integrations/issues/742

What This Branch Does

This branch adds explicit oversized-upload handling to the SBOM scan flow so 413 Request Entity Too Large responses no longer fall back to generic scan failures. It propagates the error from createAuthorizedFetch through SbomScanner and shows the right user-facing message from ScanEol.scanSbom depending on whether the SBOM came from --file or was generated locally.

413 Error Propagation

• Updates createAuthorizedFetch in src/api/apollo.client.ts to convert raw 413 responses into ApiError instances, including the retry path after a 401 token refresh.
• Extends ApiErrorCode in src/api/errors.ts with PAYLOAD_TOO_LARGE_ERROR_CODE and aligns the other API error codes behind exported constants.
• Preserves upstream ApiError values inside SbomScanner in src/api/nes.client.ts, so the command layer can distinguish oversized uploads from generic GraphQL failures.

CLI Scan Messaging

• Adds a dedicated 413 branch inside ScanEol.scanSbom in src/commands/scan/eol.ts so scans fail with a specific oversized-upload message before falling back to the existing auth/general error mapping.
• Keeps the user-facing copy local to ScanEol.getPayloadTooLargeMessage, which returns the --file message for user-supplied SBOMs and the smaller-scope guidance for generated SBOMs.
• Preserves the existing analytics path in ScanEol.scanSbom, so CLI EOL Scan Failed still records the API error code and scan timing when the server rejects the upload.

Examples

./bin/run.js scan eol --file /tmp/oversized-sbom.json

✔ Loaded SBOM file
✔ SBOM trimmed
✖ Scanning failed
 ›   Error: File exceeds the 10MB limit. Try providing a smaller or partial SBOM.

./bin/run.js scan eol --dir /tmp/sbom-node-modules-huge

✔ Generated SBOM
✔ SBOM trimmed
✖ Scanning failed
 ›   Error: Generated SBOM exceeds the 10MB upload limit. Try scanning a smaller scope (e.g. a single project or subdirectory).
