refactor(reports): flatten header hierarchy and remove all emojis

Simplified report structure for better readability and accessibility:

Changes:
- Removed 'Focus Area' and 'Work by Type' group headers
- Promoted all category headers from ### to ## (h3 → h2)
- Promoted all subsections from #### to ### (h4 → h3)
- Promoted nested subsections from ##### to #### (h5 → h4)
- Removed all emojis from section headers
- Kept 'New Lights' name unchanged (Guardian theme)

Header structure:
- # Summary (h1)
- ## Desktop, Development, etc. (h2) - promoted from h3
- ### Planned Work, Opportunistic Work (h3) - promoted from h4
- ## Other, Bot Activity, New Lights, Contributors (h2)

Impact:
- Flatter, more scannable report structure
- All project areas at same heading level
- Improved accessibility (no decorative emojis)
- Cleaner navigation in table of contents

Files modified:
- scripts/lib/markdown-generator.mjs - Header level adjustments
- scripts/lib/label-mapping.mjs - Removed emojis from categories
- Both monthly reports regenerated
