[RL] All Dynasty members have Encourage/Discourage socials

ssue Description:
In the Dynasty system, all Dynasty members have access to "Encourage" and "Discourage" interactions toward other members. According to the official pack documentation, these actions should be restricted exclusively to the Dynasty Head as part of their leadership role in managing family behavior and maintaining the Dynasty's Values. The current behavior allows any member to influence others, undermining the Dynasty Head's authority and intended gameplay mechanics.

Expected Behavior:
Based on EA's official Dynasty guide, the Dynasty Head has specific exclusive powers:

• They decide who can join the Dynasty
• They assign perks
• They encourage and discourage behavior (emphasis added)
• They choose their Heir and Outcast

Only the Dynasty Head should have access to "Encourage" and "Discourage" interactions toward other Dynasty members. Regular Dynasty members (including Heirs) should not have these interactions available.

Steps to Reproduce:

1. Create or join a Dynasty with at least three members (e.g., Dynasty Head, Heir, and a regular member).
2. Select a non-Head Dynasty member (e.g., the Heir or a regular member).
3. Click on another Dynasty member.
4. Look for "Encourage" and "Discourage" social interactions in the pie menu.
5. Attempt to use these interactions.
6. Compare with the Dynasty Head's interaction menu.

Actual Result:

• All Dynasty members (regardless of rank) have access to "Encourage" and "Discourage" interactions.
• These interactions function when used by non-Head members.
• The Dynasty Head does not have exclusive control over these behavioral influence actions.
• The intended hierarchy where only the family leader shapes the Dynasty's direction is bypassed.

Additional Notes:

• The official Dynasty guide explicitly states that the Dynasty Head's role includes handling "encourage and discourage behaviour" (exact wording from EA Help).
• Developer Q&A materials confirm the Dynasty Head is the "only one" who can set Values, purchase Perks, choose Heirs, and designate Outcasts. While Encourage/Discourage isn't explicitly listed there, it is part of the Head's described responsibilities in the official guide.
• This issue may relate to broader permission-checking bugs in the Dynasty system, where role-based access controls are not properly enforced.

Impact:
Moderate to High. This bug undermines the Dynasty Head's unique leadership role and reduces the strategic importance of becoming and remaining the Head. When any member can encourage or discourage behavior, there is less incentive to respect the Dynasty's hierarchy or work toward becoming Head. The intended power structure—where the Head guides the family toward its Values while managing potential rebellion from ambitious members—is weakened. This reduces both gameplay challenge and narrative depth for Dynasty-focused playthroughs.
