DJ-97: Restyle CBSTM03A HTML statement to professional bank palette

[devin-ai-integration]

Summary

Fixes DJ-97: replaces the neon placeholder colours in the HTML-LINES 88-level VALUE literals of app/cbl/CBSTM03A.CBL with a professional bank palette. Literal-only change — no logic/paragraph changes.

Palette mapping:

• Top banner (HTML-L10): invalid #1d1d96b3 → dark navy #0B2447 + white text
• "Bank of XYZ" address block (HTML-L15): #FFAF33 → light grey #F2F2F2
• Section bars (HTML-L30-42): #33FFD1 → light grey #E9ECEF
• Column-header cells (HTML-L47/L50/L53): #33FF5E → mid-navy #1F4E79, with white bold header text on HTML-L48/L51/L54
• Consistent cell padding 4px 8px across all styled cells (incl. HTML-L22-35, data cells L58/L61/L64)
• Column widths (25%/55%/20%) and right-aligned Amount column unchanged; all hex now valid 6-digit

Verification

• Syntax check passes: cobc -I app/cpy/ --std=ibm-strict -ftab-width=4 -fsyntax-only app/cbl/CBSTM03A.CBL
  • Note: the exact ticket command (without -ftab-width=4) fails on the unmodified baseline too, because app/cpy/CUSTREC.cpy contains tab characters that push fixed-format lines past column 72 with GnuCOBOL 3.1.2's default tab width of 8. Pre-existing, unrelated to this change; -ftab-width=4 makes it pass both before and after.
• Compiled and ran CBSTM03A/CBSTM03B locally with GnuCOBOL against app/data/ASCII/ (indexed files loaded per CREASTMT.JCL STEP010 sort/OUTREC layout); run completes rc=0 and produces valid HTML statements for all 50 cards.
• Plain-text STMTFILE output is byte-identical before vs after (cmp clean).
