refactor(DB): Consolidate small SQL files by table

[Nyeriah]

Summary

• Consolidate small SQL files (1-5 lines) that target the same database table and share the same bracket prefix into single files per table
• Reduces total SQL file count by 22 (from 230 to 208) while preserving all SQL content and comments
• Document SQL file naming conventions and organization rules in README

Brackets affected

Bracket	What was merged	Files saved
Bracket_0	6 creature files → progression_0_creature.sql	5
Bracket_61_64	2 disables + 3 item_template files	3
Bracket_70_2_1	2 61_64 down files	1
Bracket_70_2_2	2 prefix-0 creature_loot_template files	1
Bracket_70_3_1	5 61_64 down files	4
Bracket_70_4_1	4 61_64 down files + 2 loot files	5
Bracket_70_6_1	3 61_64 item_template down files	2
Bracket_80_1_1	2 creature files	1

Rules followed

1. Only merged files with the same bracket prefix (never mixed different brackets)
2. Only merged files targeting the same database table
3. Kept thematic event files (brewfest, hallows_end, etc.) separate
4. Kept files over ~50 lines as standalone
5. Preserved all original comments as section headers

Test plan

• Verify SQL files load correctly via DBUpdater on server start
• Confirm no SQL content was lost (all original statements preserved)
• Check that merged files execute without errors on a clean world database
