feat(calendars): Add Lunar Coordinate Time (TCL) plugin v2.5.2.180

Add new scientific calendar plugin lunar_tcl.py implementing the LTE440
Lunar Time Ephemeris for relativistic time between Earth and Moon.

Note: This is separate from the existing lunar_time.py (ESA LTC).

Features:

• Actual TCL clock time display (14:30:45 TCL)
• Shows what time a clock on the Moon would display
• Daily drift ~56.7 µs/day (Moon clock runs faster)
• Multiple display formats: Time, DateTime, Time+Drift, Drift only
• 13 periodic variations (annual ~1.65ms, monthly ~126µs)
• Full 12-language translation support
• Fixed config_flow dropdown labels with emojis

Updated ESA Lunar Time (lunar_time.py):

• Config options now show emoji labels for landing sites
• Improved dropdown descriptions

Based on:

• Paper: Lu, Yang & Xie (2025) A&A 704, A76
• DOI: 10.1051/0004-6361/202557345
• Data: JPL DE440 ephemeris

Implements IAU 2024 Resolution II (LCRS/TCL standard)

• Multiple display formats (µs/day, ns/day, ratio, accumulated)
• Configurable precision and calibration options
• Full 12-language translation support
