fix: make Tesla action commands case-insensitive

[0xbyt4]

Summary

This PR fixes case-sensitive string comparison in DIMOTeslaConnector that caused Tesla commands to fail when LLM output had different capitalization.

Problem

File: src/actions/dimo/connector/tesla.py

The connector compared action strings with exact match:

if output_interface.action == "lock doors":  # Only lowercase worked
    ...

Impact:

• LLM outputs like "Lock Doors", "LOCK DOORS", "Lock doors" all failed
• Commands silently failed with "Unknown action" error
• Users had no indication why their command didn't work

Root Cause

LLM models don't guarantee consistent casing in their outputs. The same prompt might return:

• "lock doors" (lowercase)
• "Lock Doors" (title case)
• "LOCK DOORS" (uppercase)
• "Lock doors" (sentence case)

Solution

Normalize the action string to lowercase before comparison:

# Normalize action to lowercase for case-insensitive comparison
action = str(output_interface.action).lower()

if action == "lock doors":
    ...

Testing

Added comprehensive test suite in tests/actions/dimo/test_tesla.py with 19 test cases:

Command	Test Cases
lock doors	"lock doors", "Lock Doors", "LOCK DOORS", "Lock doors", "lOcK dOoRs"
unlock doors	"unlock doors", "Unlock Doors", "UNLOCK DOORS"
open frunk	"open frunk", "Open Frunk", "OPEN FRUNK"
open trunk	"open trunk", "Open Trunk", "OPEN TRUNK"
idle	"idle", "Idle", "IDLE"

Plus basic tests for unknown actions and missing JWT handling.

Test Results:
