fix: deduplicator and add Bugzilla component configuration

**Real-world bugs fixed:**

1. **Deduplicator crash** (binary_part out of range):
   - normalize_body() was trying to slice AFTER replacements
   - Fixed: compute byte_size of normalized string first
   - Now safely handles any length input

2. **Bugzilla component configuration:**
   - Added --component and --version CLI flags
   - Made component/version configurable per submission
   - Better defaults (distribution/rawhide instead of hardcoded)

3. **Bugzilla credentials:**
   - Added load_bugzilla_creds() to Credentials module
   - Supports BUGZILLA_API_KEY environment variable
   - Also supports BUGZILLA_USERNAME/PASSWORD

**VALIDATED WITH REAL SUBMISSION:**
✅ Successfully filed Bug #2437503 to Fedora Bugzilla
✅ maliit-keyboard crash loop reported
✅ Full end-to-end workflow working
