* docs: add SimpleX name registration guide
* docs: clarify SimpleX name registration steps
Explain why registration needs two on-chain transactions with a wait
(commit-reveal prevents someone from grabbing the name mid-registration).
Mark attaching both contact and channel links as advanced usage.
* docs: switch name guide to official dapp, apply review
Use testing-names.simplex.chat and its simpler flow (both SimpleX
contact/channel fields on Create your profile; no Add profile fields
modal). Apply @epoberezkin review suggestions (intro, testing page URL,
'main names launch', claim purpose).
* Apply suggestions from code review

* docs: light screenshots, update name flow diagram
Use light-theme official-dapp screenshots. Rework the flow diagram:
drop the 'both' branch, split contact vs channel before step 4 (each
set in its own window), and match the reviewed connect wording (search
or type the name).
