fix(examples): address PR #105 review comments (#106)

## Summary

Addresses open review comments from #105 (deprecated model removal):

- Increase `express.json()` body size limit to 50mb so base64 data URL
payloads don't hit the default 100KB cap
- Remove 3 duplicate example files (`text-to-image.ts`,
`text-to-video.ts`, `image-to-video.ts`) that were repurposed during
model removal but became identical to existing examples with misleading
names
- Update `examples/sdk-core/README.md` references accordingly

## Test plan

- [ ] Verify express example starts without errors
- [ ] Verify no broken references to deleted files remain

> [!NOTE]
> **Low Risk**
> Low risk: changes are confined to example code and documentation,
mainly increasing request body size and deleting redundant example
scripts.
> 
> **Overview**
> Updates the `examples/express-api` server to accept large base64
payloads by raising the `express.json()` body limit to `50mb`.
> 
> Cleans up `examples/sdk-core` by removing three redundant/misleading
example scripts (`image/text-to-image.ts`, `video/text-to-video.ts`,
`video/image-to-video.ts`) and updating the README to point to the
remaining `image-to-image` and `video-to-video` examples.
