Currently, we type our fractional index keys as `string` and don't have
any validation for them. I'm touching some of this code for my work on
line handles and wanted to change that:
- fractional indexes are now `IndexKey`s, not `string`s. `IndexKey`s
have a brand property so can't be used interchangeably with strings
(like our IDs)
- There's a new `T.indexKey` validator which we can use in our
validations to make sure we don't end up with nonsense keys.

### Change Type
- [x] `patch` — Bug fix
### Test Plan
1. Mostly relying on unit & end to end tests here - no user facing
changes.
- [x] Unit Tests
Adds validation for urls we use for our shapes and assets. This PR
includes a migration so we should check that existing rooms still load
correctly. There might be some that won't, but that means that they had
invalid url set.
### Change Type
- [x] `patch` — Bug fix
- [ ] `minor` — New feature
- [ ] `major` — Breaking change
- [ ] `dependencies` — Changes to package dependencies[^1]
- [ ] `documentation` — Changes to the documentation only[^2]
- [ ] `tests` — Changes to any test code only[^2]
- [ ] `internal` — Any other changes that don't affect the published
package[^2]
- [ ] I don't know
[^1]: publishes a `patch` release, for devDependencies use `internal`
[^2]: will not publish a new version
### Test Plan
1. Existing rooms should still load correctly (there should be no
validation errors).
2. Adding new images and videos should also work (test both local and
multiplayer rooms as they handle assets differently).
- [x] Unit Tests
- [ ] End to end tests
### Release Notes
- Add validation to urls.
