Added — Bot Auth System

Bots can now play along with a login-wall plugin instead of sitting there unauthenticated. Off by default (auth.enabled: false); needs database.enabled: true to remember passwords across joins.

• Auto-register / auto-login: on a bot's first join it generates a strong random password, encrypts and stores it (AES-256/GCM, key in auth.key in the plugin data folder, never in config.yml or logs), then sends auth.register-command as the bot after a randomized human-like delay. Every later join sends auth.login-command with the same remembered password instead.
• Works against any login plugin built around a /register <password> <password> / /login <password> command shape — the defaults already match nLogin, AuthMe, LoginSecurity, CrazyLogin, and xAuth. Commands are replayed exactly like a real client's typed chat command (through PlayerCommandPreprocessEvent), not a bare command dispatch, so plugins that hook that event directly (most login plugins, including nLogin) still see the attempt.
• Dedicated nLogin integration: nLogin's command path throws for a bot's connection no matter what, so it's authenticated through nLogin's own public API instead — fully optional, inert if nLogin isn't installed.
• A bot stands still and doesn't turn its head from the moment it joins until its register/login outcome is known (read from the login plugin's own reply — chat, title, subtitle, or action bar), exactly like a real not-yet-authenticated player; auth.pending-timeout-ticks is the hard fallback so an unrecognized response never leaves a bot stuck frozen.
• New /fpp auth command: on/off, status [bot], reset <bot>, setpassword <bot> <password>. New permission fpp.auth (default op, included in fpp.op).
• New settings GUI category (🔐 ᴀᴜᴛʜ): toggle, register/login command templates, delay/timeout ticks, and password length/complexity — see Configuration.

Added — "Bot Console" Color Theme

Every chat message, GUI, and console log now pulls from one consistent violet/lime palette instead of the scattered ad-hoc colors (blue accents, plain named colors, mismatched grays) used previously. Purely visual — no config or permission changes.

• Chat/GUI text: violet (#A78BFA) primary accent, lime (#BAFF4F) success/highlight, red (#FF6A5C) errors, plus a consistent ink/mute/mute-2/line neutral scale for body text, captions, and dividers.
• Console output (FppLogger, the startup/shutdown banners) recolored to match with true-color ANSI.
• language/en.yml's header now documents the full palette for anyone customizing messages by hand.

Added — Auth & Perf Settings/Help Categories

• The settings GUI (/fpp settings) gained a 🔐 ᴀᴜᴛʜ and a 📈 ᴘᴇʀꜰ category (general, body, auth, perf, debug) — the perf category exposes every performance.* config option, including the self-profiler, with changes restarting the monitor live instead of requiring /fpp reload.
• The help GUI (/fpp help) split auth and perf out of the catch-all ᴄᴏʀᴇ category into their own tabs, each with a distinct accent color.
