Email fixes

[hatch01]

Fixed ui to send email:

• now editing bar is on the bottom sticked to the keyboard
• the attachments are so moved to the top of the screen
• the ui is as much as I can responsive and use less fixed sizes
• sending attachments work back
• there is now an indicator to say that the email is sending and sended

in reading email:

• fixed the background color of the web view in dark-reader

in logic :

• deleted some duplicate code in email cubit
• use a send cubit to easily share controller etc

Would it be possible to also fix the bug where sent emails don't show in the "Sent Emails" tab ?
The changelog seems great otherwise
