feat(Employee Advance): add 'Returned' and 'Partly Claimed and Returned' status

[ruchamahabal]

Problem:

The main usage of Employee Advance is to allocate it against Expense Claims. Currently, advance only maintains a status for "Claimed" and while allocating advances against a claim, there are two more types of advances that are shown in the list for selection but should not be available for allocation:

• Returned: Entire amount which was paid for the advance is returned, leaving nothing to be claimed.
• Partly Claimed and Returned: Some part of the advance is claimed, rest is returned, leaving nothing to be claimed.

Changes:

• Add status Returned and Partly Claimed and Returned to Employee Advance so that it's easier to track and allocate. Filter and get advances that don't have Claimed/Returned/Partly Claimed and Returned status for allocation in expenses.

• Set title, document states for Employee Advance

  Before:
  

  After:
  

• In Expense Claim, advances should be validated after setting totals since they are validated against the total claimed amount. Else, it raises an incorrect validation error.

• Patch and test status
