Fixes #458

Short description of what this resolves:

This PR fixes server-side 500 errors caused by inconsistent module imports of the OBA SDK. Standardizing the import pattern ensures reliable module resolution during SSR.

Changes proposed in this pull request:

• Fixed inconsistent imports of the OBA SDK across server-side files
• Replaced usages of $lib/obaSdk.js with $lib/obaSdk to align with Vite/SvelteKit module resolution
• Eliminated runtime import failures that were causing intermittent server 500 errors
• Improved consistency and reliability of server-side code

Files updated:

• src/lib/serverCache.js
• src/routes/stops/[stopID]/+page.server.js
• Multiple API route files under src/routes/api/oba///+server.js
