ui: simplify element-calling port modal — trim verbose steps and remove extra verification task

- Replace 3 long instruction bullets with 1 plaintext line
- Shorten intro (drop long parenthetical on IP location)
- Remove 'how to confirm it worked' note — if router applies rules, ports are open
- Keep port table intact (40000-40099 current set)
