fix: handle Schlage masked usercode responses with varying PIN lengths

[raman325]

Summary

This PR fixes an issue with Schlage locks that have PINs with lengths other than 4 digits. The masked usercode response uses repeated characters (e.g., "**********" or "0000000000") which need to be detected regardless of length.

Breaking change

None.

Proposed change

Coordinator changes (coordinator.py)

• Use len(set(usercode)) == 1 to detect any single-character repeated pattern for masked responses
• Check that masked response doesn't match the actual PIN before treating as empty
• Add break after clearing usercode to exit loop early

Z-Wave JS Provider changes (zwave_js.py)

• Simplify the cleared usercode verification logic
• Move debug log to else block after successful clear operation
• Return False when verification fails to properly trigger retry logic

Style fixes

• Convert lists to tuples in for loops (pylint R6102) in:
  • __init__.py
  • coordinator.py
  • migrate.py

Type of change

• Bugfix (non-breaking change which fixes an issue)

Additional information

• This PR fixes Schlage locks with non-4-digit PINs
• Tests: 360 passed, 84.61% coverage

Pull request overview

This PR adds support for Yale locks which use a different masked usercode format ("0000") compared to Schlage locks ("**********"), and fixes an issue with clearing codes on Schlage locks.

Changes:

• Added Yale masked usercode detection using len(set(usercode)) == 1 to detect any single-character repeated pattern
• Improved Z-Wave JS provider's clear operation by moving debug log to else block and returning False on verification failure
• Applied pylint style fixes converting lists to tuples in for loops across multiple files
