Set max target limit to 50 (#2320)

## Description

<!-- What changed? Why? (the code + comments should speak for itself on
the "how") -->

<!-- Fun screenshots or a cool video or something are super helpful as
well. If this touches platform-specific behavior, this is where test
evidence should be collected. -->

<!-- Any issues this pull request closes or pull requests this
supersedes should be linked with `Closes #issuenumber`. -->

closes #2318
closes #2319 

For the 2027 game, teams might want to detect more than 10 results.
Therefore, we're increasing the limit.

We also ran into an issue with our sim, where a user can create too many
objects and cause an overflow. We implement that same limit of 50
targets here.

Merge checklist:
- [x] Pull Request title is [short, imperative
summary](https://cbea.ms/git-commit/) of proposed changes
- [x] The description documents the _what_ and _why_
- [ ] If this PR changes behavior or adds a feature, user documentation
is updated
- [ ] If this PR touches photon-serde, all messages have been
regenerated and hashes have not changed unexpectedly
- [ ] If this PR touches configuration, this is backwards compatible
with settings back to v2025.3.2
- [ ] If this PR touches pipeline settings or anything related to data
exchange, the frontend typing is updated
- [ ] If this PR addresses a bug, a regression test for it is added
