fix: Set complete contact details for Employee in PE (backport #46683)

[mergify]

Issue: Contact details not auto-completing when party type is Employee

Root Cause:

1. Can't create a Contact document for Employee type
2. Employee contact details are stored directly in the Employee document rather than a separate Contact

Changes Implemented:

• Updated depends_on conditions for Contact Person and Contact Email fields to support Employee party type
• Added auto-completion of contact details for Employee party type

Note

Backport to version-15 and version-14
