Allow sending text after `shrug`

¯\_(ツ)_/¯ IDK, I like to write something after, sometimes

Allow sending:

¯\_(ツ)_/¯ some text

By entering:

/shrug some text

It's supported in Element. If you did it in nheko, you just used to lose the
extra text.

Not putting text is still supported, a ternary operator makes sure a
space is only inserted if the text isn't empty, to avoid having a trailing
space.

Improve wording in multiple strings.

This is for consistency with "Start a private chat", and is more
specific.

This is less ambiguous. Moreover, this mode might be useful on a
computer touchscreen.

This is less ambiguous, as it aligns with the other uses.

Trusted might refer to something else, like the reputation project.
You can trust a user you haven't verified.

Also mention devices as this shares keys with verified devices, for when device
verification was performed without cross-signing.

Replace it with "verification process".
