UIs - Sync changes from legal name branch + integrate use of FF

[argush3]

Ensure that the latest legal name changes are pulled into main branch such that we are able to use legalName and alternateNames list field appropriately for firms.

It will also be necessary to ensure that this work is able to be turned on/off via a FE FF(enable-legal-name-fix ).

For development purposes, if the BE is not ready, the GCP dev environment can be used for testing purposes while testing locally temporarily. The business response should be the same as what we will be returning for the easy legal name fix. The final verification will need to be against the updates made in main.

TODOs

• [ ] Sync code from legal name branch into main
• [ ] Update legal name code in main to work with enable-legal-name-fix FE FF. If FF has not been added, get someone with access to add it.
  • [ ] Filings UI
  • [ ] Create UI
  • [ ] Edit UI
• [ ] Add/update tests as appropriate
• [ ] Once deployed to dev, verify things work as expected when toggling FF. Will need to coordinate with BE to ensure BE & FE enable-legal-name-fix FFs are toggled to same value and at same time.
