Prefect 3.8: the redesigned UI ships by default

The redesigned UI is the default for self-hosted servers. Run Prefect yourself and you now get the V2 interface out of the box, with no opt-in required. (#22519)

Also in this release:

Copy to new run. Re-run a flow straight from the run menu with its options carried over.#22565 #22567

Clickable log links. URLs in run logs are now links you can follow.#22496

Easier date inputs. Pick a year and month, or type a date directly, when filtering runs.#22495

Deployment filters on triggers. Flow run triggers can scope to specific deployments.#22319

Run watch survives reconnects. Following a flow run keeps going across stream disconnects.#22550

No leaked concurrency slots. A cancelled slot acquisition no longer leaves a slot reserved.#22542

The full release notes cover every change, including bug fixes.
