526 contrasting confirmation messages

[Kafui123]

Fixes issue #526

Changes:

• Fixed the issue where an error message was shown, but a successful flash confirmation still appeared afterward. Now the feedback is consistent... no mixed signals for the user.
• Adjusted the logic so that success and failure states are clearly separated and reported correctly, instead of overlapping or triggering both paths.
• Addressed the case where email sending could fail, but the form would still be created, which previously caused a misleading failure message even though the form existed.
• Ensured that form creation and email sending happen within a single transaction block.

Testing:

• Click on administration and then manage terms.
• Select a valid term under any academic year.
• Create a new labor status form and then click submit
• If everything succeeded, no flash error message would appear
• If the form got created, but no email was sent, the form would not get created.
