feat: SpeedyBot v4.0.0 — Control Center & Growth Suite

[roseshayan]

SpeedyBot v4.0.0

Major product/operations release built as an additive extension layer over the stable v3 core.

Highlights

• modular app.py + speedybot_v4/ runtime while keeping main.py stable;
• redesigned customer account, categorized storefront and admin Control Center;
• Telegram official button styles + optional Custom/Premium Emoji IDs;
• Normal / Sales Paused / Maintenance modes;
• user purchase/trial blacklist with reason;
• plan categories;
• per-user Trial GB/days/IP overrides;
• customer star feedback + comments + analytics;
• targeted broadcast audience segments;
• SQLite Audit Log + optional Telegram audit channel;
• read-only 3x-ui client snapshot;
• self-safe modular updater with backup/rollback;
• v4 unit tests and expanded CI;
• complete English/Persian documentation and release notes.

Safety

• No required new environment variable.
• Existing .env and speedping.db are preserved.
• v4 migration is additive.
• Panel snapshot is intentionally read-only.
• This PR does not modify the stable v3 main.py business core.
