AttributeError: 'Plex' object has no attribute 'remove_label' when kometa_integration=true

[sjabby]

This is for the mediux-api branch

Describe the bug
When kometa_integration = true is set in the configuration, the application crashes with an AttributeError because the remove_label method is not implemented in the Plex service class.

To Reproduce

Set kometa_integration = true in ~/.config/mediux-posters/settings.toml
Run any sync operation (e.g., mediux-posters sync)
Wait for the application to download and attempt to upload images
See error when it tries to remove Overlay labels

Expected behavior
When kometa_integration = true, the application should successfully remove the "Overlay" label from media items after uploading posters/backdrops without crashing.
Screenshots
N/A - This is a code error, not a visual issue.
Additional context

Version: mediux-posters v0.5.0
Python: 3.11.11
Branch: mediux-api
Installation method: pipx

Workaround: Setting kometa_integration = false allows the application to work correctly.
Technical details: The error occurs in /services/plex/service.py line 333 where self.remove_label("Overlay", object_id=object_id) is called, but this method doesn't exist in the Plex class.

[Buried-In-Code]

Good spot, thats a small spelling issue it should have been self.remove_labels surprised it wasn't raised as an error in my IDE, will get this fixed
