Refactors URL slug case sensitivity implementation:
- Moves case conversion to creation time instead of lookup
- Updates middleware to handle case sensitivity more efficiently
- Adds configuration docs for case sensitivity and list query limits
- Simplifies nanoid implementation to always use lowercase
This change improves performance and consistency in URL handling while maintaining backwards compatibility with existing links.
Extracts list query limit into runtime configuration
Updates default pagination limit in query schema
Makes the list query limit configurable across the application rather than hardcoding it to 500, improving flexibility for different deployment scenarios.
