Add pricing FAQ items for credits and update member info

[Alek99]

This PR adds two new FAQ items to the pricing page:

1. If I upgrade my tier, do I get the extra credits immediately? - Clarifies that credits are added immediately upon tier upgrade
2. Do credits ever expire? - Explains that credits only reset on Free tier and roll over on Pro tiers

Also updates the member addition FAQ to clarify it's only available on the Enterprise tier.

Greptile Overview

Greptile Summary

This PR enhances the pricing FAQ section by adding two helpful new items about credit behavior and clarifying member management limitations.

Key Changes:

• Added FAQ explaining immediate credit addition upon tier upgrades
• Added FAQ clarifying that credits only reset on Free tier and roll over on Pro tiers
• Updated member addition FAQ to specify it's only available on Enterprise tier
• Removed the generic billing determination FAQ (previously at lines 110-112)

Issues Found:

• Tier naming inconsistency: Uses "Tier 25" and "Tier 50" instead of the standard "Pro 25" and "Pro 50" naming from PRO_TIERS_TABLE
• Incorrect credit amount: States 1,000 additional credits when upgrading from Pro 25 to Pro 50, but the actual difference is 500 credits (500→1000)

Confidence Score: 3/5

• Safe to merge after fixing tier naming and credit amount inaccuracies
• The changes are straightforward FAQ updates with no logic changes, but contain factual errors about tier names and credit amounts that could confuse users
• pcweb/pages/pricing/faq.py - fix tier naming and credit amounts to match PRO_TIERS_TABLE constants
