Implemented automatic posting of transaction notifications to #transaction-log
channel when transactions are submitted via /dropadd or /ilmove commands.
**New Utility:**
- `utils/transaction_logging.py` - Centralized transaction logging function
- `post_transaction_to_log()` - Posts transaction embed to #transaction-log
- Uses team's ML affiliate for consistent branding
- Displays team thumbnail, colors, and player moves
- Shows season from transaction data (not hardcoded)
- Format matches legacy transaction log embeds
**Integration Points:**
- `/dropadd` (scheduled transactions) - Posts when submitted
- `/ilmove` (immediate transactions) - Posts when executed
- Both use shared `post_transaction_to_log()` function
**Embed Format:**
```
Week 18 Transaction
[Team Name]
Player Moves:
- **PlayerName** (sWAR) from OLDTEAM to NEWTEAM
- **PlayerName** (sWAR) from OLDTEAM to NEWTEAM
[Team Thumbnail]
Footer: "SBa Season 12" with SBA logo
```
**Features:**
- Automatic ML affiliate lookup for consistent team display
- Team colors and thumbnails in embeds
- Season number from transaction data
- Graceful error handling (logs warnings, doesn't block submission)
- Matches legacy embed format exactly
**Files Changed:**
- NEW: `utils/transaction_logging.py` - Transaction logging utility
- MODIFIED: `views/transaction_embed.py` - Added logging calls on submission
**Testing:**
- Transaction builder tests pass (31/31)
- No new test failures introduced
- Logging is non-blocking (submission succeeds even if logging fails)
