move everything to joins page, update search/default page, etc (#82)

## Summary
I have moved everything from `/models/model_name` to `/joins/join_name`.
I also created a shared entity object and show groupbys and joins in
search results. PR walkthrough video
[here](https://drive.google.com/file/d/10lnso4MGXuXlmr5F-aLzDBwWncGBuEmt/view?usp=sharing)

Limitations:
- You can't click on a model or groupby from search
- Backend search only queries models (so matches to joins or groupbys do
not come up)
([details](https://github.com/zipline-ai/chronon/pull/82/files#r1855120136))

Future:
- Removing anything not related to joins (model performance, skew, etc)

## Checklist
- [x] Added Unit Tests
- [x] Covered by existing CI
- [ ] Integration tested
- [ ] Documentation update

## Release Notes

- **New Features**
- Enhanced navigation with dynamic filtering of entities in the
NavigationBar.
- Introduced a detailed table view for "Joins" displaying relevant model
information.

- **Bug Fixes**
  - Updated redirection from the root URL to the "Joins" page.

- **Removals**
- Removed outdated placeholder components for "GroupBys" and "Models"
pages.

These updates improve user navigation and provide a more informative
interface for managing joins and models.
