Feature Request | Enhance Bot Settings: Category-Based Whitelist / Blacklist for Coins

Description
Currently, in the Bot Settings page, the Whitelist and Blacklist fields only support free-text input for adding individual coins. This makes management difficult, error-prone, and hard to track from a user experience perspective—especially when users want to exclude or include entire groups of coins.

Proposed Enhancement
Add the ability to whitelist or blacklist coins by category in addition to (or instead of) free-text input.

Feature Details
- Introduce a predefined list of coin categories (e.g. Meme Coins, DeFi, Layer 1, AI, Gaming, etc.).
- Categories should be selectable via:
- Dropdown
- Multi-select
- Or similar UI control
- When a category is selected:
- Blacklist → all coins belonging to that category are excluded from trading.
- Whitelist → only coins belonging to that category are allowed for trading.
- The category selection should dynamically apply to all current and future coins within that category.Example Use Case
- A user does not want their bots to trade meme coins.
- User selects “Meme Coins” in the Blacklist Categories option.
- All meme coins automatically become non-tradable without needing to manually maintain a list.Expected Benefits
- Improved user experience and clarity
- Easier bot configuration and maintenance
- Reduced human error from manual text input
- Better scalability as new coins are addedAcceptance Criteria
- Users can select one or multiple categories for whitelist and/or blacklist.
- Selected categories correctly apply to all coins in those categories.
- Existing free-text input remains functional (optional but preferred).
- UI clearly shows selected categories and their effect.Additional Notes
This feature would significantly simplify bot setup and make trading preferences easier to manage, especially for users running multiple bots.
