Pale yellow headers on campaign-end composition tables

Matches the pale yellow (#fdf6d8) already used for analytical table
headers elsewhere in the app. Added an optional header_bg param to
_composition_table (live preview) and passed the same color to
_docx_table (docx) for the Sector/Function/Seniority/Country tables
specifically, leaving the one other _composition_table call site
(Reports tab's compact card) untouched.
