refactor: Remove Playwright dependency completely from project

- Replace Playwright base image with python:3.12-slim in Dockerfile
- Remove playwright from pyproject.toml dependencies
- Remove ensure_playwright_browsers() function from mcp_server_main.py
- Delete KİK v1 client files (client.py, models.py) - v2 uses httpx
- Delete postinstall.sh Playwright installation script
- Delete obsolete setup.py and requirements.txt.bak
- Remove saidsurucu-yargi-mcp-f5fa007 snapshot directory
- Update client_v2.py docstring to reflect httpx usage
- Regenerate uv.lock without playwright

KİK v2 now uses pure httpx for all HTTP operations with SSL legacy support.
