Improve profile edition

[felipecalvo]

:dart: Goal

Improve the edit profile view per @cucusita's suggestions.

:memo: Details

• The fields are shorter in width, so they don't take the full page anymore.
• The "Please fill your profile data" toast (which disappeared fairly quickly) was replaced with a more prominent info alert, which can be closed.
• The save button is now exclusively at the bottom, both on desktop and mobile views.
• The cancel button now has an outline style.
