feat: enhance resource scheduling logs with clear status and configuration details (#18684)

* improve: enhance queue scheduling logs with clear status and configuration details

- Show specific configuration parameters (max_concurrency, max_running_queries)
- Display current resource usage (X/Y slots used)
- Include queue length and wait times for better visibility
- Distinguish between workload group and warehouse limits with clear [BLOCKED]/[ACQUIRED] status

* fix: use saturating_sub to prevent underflow in permit calculation

- Replace subtraction with saturating_sub to avoid potential underflow
- Simplify variable naming for better readability
- Ensure thread-safe calculation of used slots

* fix: update all status messages to use clear BLOCKED format

- Replace remaining generic status messages with specific blocked status
- Update workload group global semaphore acquisition message
- Ensure all code paths show detailed configuration information

* test: add workload group concurrency status logging test

- Add test to verify status messages during workload group concurrency limits
- Simulate 100 concurrent queries with max_concurrency=16
- Capture and log status messages for debugging queue behavior

* clean: remove test case and unused imports

* feat: add queries waiting count to all BLOCKED status messages

- Add queue length to workload group local limit messages
- Add queue length to workload group global limit messages
- Ensure consistency with warehouse limit messages that already show waiting count

* refactor: change BLOCKED to WAITING for friendlier status messages

- Replace [BLOCKED] with [WAITING] prefix for all queue status messages
- More user-friendly indication that queries are waiting rather than blocked
