Trim whitespace from admin detail fields before saving

[geominorai]

Trims leading/trailing whitespace from admin name, email, and auth ID fields from POST parameters

Motivation and Context

Fields were not trimmed and were allowed to persist into the DB like this, which can cause problems later when read out for use as-is without sanitization. AuthID in particular can store whitespace without being noticed since the field gets trimmed before being displayed on the page.

How Has This Been Tested?

Tested on Apache web server
Edited admin detail with a copious amount of leading/trailing whitespace in the fields are now properly trimmed.
