Ports dropdown in formpage does not reload after clicking refresh

• Caching in form is not reloaded after reopening.
• Port refresh button is not reloading the port dropdown.

To reproduce:

1. Open (for example) a create lightpath form
2. Close form
3. Create new SP for a customer
4. Reopen create lightpath form
5. Dropdown does not contain the newly created port
6. Try refreshing the port dropdown

Fix is to reload page, this will clear the cache, and the dropdown will contain the newly created port.

Consider fixing this in the Pydantic form
