KLCO CP204 filer

For KLCO staff only. PracticeOS (base.klcogroup.my) hands this extension a list of companies whose CP204 estimate is approved. In the staff member's own logged-in MyTax session, the extension opens each company's CP204 draft, fills it in and stops at the declaration page. The staff member reads it and signs it themselves; the extension never signs or submits. After the staff member signs, it saves the filed form and LHDN's acknowledgement slip back to PracticeOS. It does nothing unless started from PracticeOS by a signed-in KLCO staff member.
