glitches with no_email workflow

[kosarko]

1. The email variables are not interpolated...I got this:

   
   Confirmation e-mail:    https://someplace.example.com//login/autoregistration?verification-token=NOT_A_REAL_TOKEN

---

${dspace.name}, WWW: ${dspace.url} Email: ${lr.help.mail} Tel.: ${lr.help.phone}

note the footer/signature
2. Seems there's an issue with the email regexp (I was not able to use `email+dspace7test@gmail.com`; the plus sign seems to be an issue; but needs to be verified)
3. Welcome login page contains fillers that should be replaced by real values (I think I saw some Lorem Ipsum on another page).

When I click the link in email, I get a something went wrong red bubble.

When I tested this the first time today, I got the red bubble as well as the agreement/welcome - I could confirm that and continue. When recording in an anonymous window the agreement/welcome was not shown

P.S. The email template is still not interpolated correctly; but that's also tracked in #1099

• [ ] https://github.com/ufal/clarin-dspace/issues/1060#issuecomment-2066447424 (red bubble) still valid

• [x] the email is better; but:

  DSpace repository account at {params[5]},

=> dataquest-dev/DSpace#703
