Pi-hole updates FTL v6.8, Web v6.6.1 and Core v6.5

Pi-hole FTL v6.8, Web v6.6.1 and Core v6.5 fix several high-severity issues, including crafted-PID command execution, unsafe root-level file handling and Teleporter document-root relocation.

FTL v6.8 also fixes authenticated data exposure paths, cross-site API requests on passwordless installations, and an API TXT-buffer out-of-bounds write.

The release changes live logging to a ring buffer, adds punycode support for internationalised list domains, and applies stricter configuration, symlink and database-retention rules.

Web v6.6.1 adds validation and Query Log fixes, while Core v6.5 updates gravity handling, local file adlist processing and database schema performance.
