* reword 'QR code' to 'Invite Code'
* reword adding classic email
* remove the 'new contact' things together
* add 'new classic contact' shortcut only for non-chatmail; it is still always available in the three-dot menu of 'new contact'
* use same menu for qr show/scan
* add 'new classic contact'
* remove 'scan' button from 'new classic contact' (ppl usually came from 'scan')
* rename to 'add contact manually'
* stay with 'qr code' for now
* add submenu to 'Explore Other Options'
* move 'Manual Login' to 'Explore Other Options'
* clearer titles, even if they are repetive
* move 'Scan QR' to 'Other'; this allows us to make 'Other' more outstanding
* cleanup layout
* tweak wording to 'Use Other Server' pointing to 'List in Browser', 'Classic Login', 'Scan Invite Code'
* use a standard secondary button for 'Use Other Server'
* show default onboarding server name
* reword to 'List Chatmail Servers'
* always close other-sign-up-options on tapping an option
* clarify that 'classic login' is about e-mail
'Signature' is very much related to email, sth. below the text,
this is not the case for Delta Chat, esp. not when using chatmail
'Status' implies that others may be aware of changes,
which is not the case as well.
therefore we'll try 'Bio' - which is also used by by 'Telegram', 'Github', 'Mastodon';
(whatsapp and signal use 'About', but we were failing to get a good hint for that :)
with chatmail, providers exist that allow to send encrypted mails only.
pulling in the system address book unconditionally for chatmail will harm UX
as for most of these addresses,
no public key will be known until eg. a QR code is scanned.
we may think this over in the future.
note, that one usually also can create a Delta Chat chat from the address book,
so, this works also without having Delta Chat pulled in all addresses
(which has some issues, https://github.com/deltachat/deltachat-android/issues/2923 )
