Incremental ID

Issue Description

Implement an incremental ShortID generation system combining alphanumeric characters to create unique identifiers.
Design Doc: https://docs.google.com/document/d/1FdrxtEER7r85vKCEb86_RhkuSV-EVN6JBaxmGnJFBLQ/edit?usp=sharing

Expected Behavior

The system should generate ShortIDs sequentially according to the following phases:

1. Initial Phase (T-1 to T-1000): Numeric increment from T-1 to T-1000.
2. Alphabetic Phase (T-1A to T-1000Z): Append uppercase letters after reaching T-1000.
3. Lowercase Alphabetic Phase (T-1a to T-1000z): Use lowercase letters after exhausting uppercase alphabets.
4. Combination Phase (Task-1Aa to Task-1000Zz): Combine uppercase and lowercase alphabets for further scalability.

Current Behavior

Database uses document ID to access the task
