change default vite port and add strictport

[atterpac]

Description

Commit changes the default vite port to :9245 to help avoid conflicts when users are already running something on the default vite port.
Also sets vite port to strict so vite will error if this port is not available.

Adjusted taskfile to match port

Thank you, that was quick! 👍

Some templates (e.g. vanilla) still use the port 5173, because they have no vite.config.js

$ wails3 init -t vanilla -n myapp
$ cd myapp
$ wails3 dev
...

Good catch those vite configs should be added now

Could we test for the env var WAILS_VITE_PORT and default to a hard coded port if unavailable? This means it could be set in the task file with no mismatch.
