Invalid check for Lucky Miner LV07

[chrigublaser]

Describe the bug
Lucky Miner LV07 devices are not being recognized due to an incorrect string check for this model in factory.py.
The current logic checks for "Lucky miner" (lowercase m), which works for LV08, but the LV07 returns "Lucky Miner" (uppercase M) in web_text, causing identification to fail.

To Reproduce

1. Install pyasic following the Getting Started guide.
2. Fetch miner information by IP as described in:
   https://github.com/UpstreamData/pyasic?tab=readme-ov-file#creating-miners-based-on-ip
3. Observe that the miner is not recognized → result is None.

Expected behavior
The miner should be detected and identified as Lucky Miner LV07 (Stock).

Miner Information (If applicable):

• Manufacturer: Lucky Miner
• Type: LV07
• Firmware Type: Stock
• Firmware Version: 1.1.0

Additional context
pyasic calls _get_miner_web from factory.py to retrieve miner data and determine the miner type.
For Lucky Miner devices, the detection relies on the presence of "Lucky miner" in web_text.

LV08 web_text contains: "Lucky miner" → recognized correctly
LV07 web_text contains: "Lucky Miner" → not recognized due to case-sensitive match

This causes LV07 miners to go unidentified.
