Improve UX for token allowance updates on plan upgrades

Issue

When users upgrade to a larger plan that includes more tokens, they are charged immediately but must wait until the 1st of the next month to actually use the increased token allowance. This creates a poor user experience where users pay for benefits they cannot immediately access.

Description

Consider improving the timing or communication around token allowance increases on plan upgrades. Users should either:

• Receive the increased token allowance immediately upon upgrade, or
• Be clearly informed about the waiting period before being charged

This would prevent the "feels bad" moment when users are billed but cannot yet benefit from their upgraded plan.
