TASK-US9 input field to send registration key 78

[JRB958]

this PR has:

• Creation of "send key" button visible only for company employees' dashboard to send a registration key to a user for a specific available unit which sends it by email to the user.
• Creation of "submit key" button visible only to public profiles where they add the registration key and they get assigned to a unit as renters or owners.
• Minor bug fix for updating company user profile
• Minor UI updates like adding page titles clearly
• updated the e2e cypress testing to pass the check with property addition (property-units)

Notes: there's a known bug that doesn't allow the registration key to work form my computer (send or submit), but works from the backend developer's computer. it's being worked on currently #169 and #175

jest testing (react unit testing) passing

all the e2e testing passing

the high repetition percentage is unavoidable since it's in a testing file (end to end testing) where many commands must be repeated with the same structure..
