[REFACTOR] Move Hardcoded Value to Constant for Max Invitations

[ThisIsMani]

Feature Description

Here:

hyperswitch/crates/router/src/core/user.rs

Line 501 in b236441

if requests.len() > 10 {

In the current implementation, the value 10 is hardcoded when checking the number of invite requests in the code. To improve maintainability and avoid magic numbers, this value should be moved to a constant in crates/router/src/consts/user.rs.

Possible Implementation

• Create a new constant in crates/router/src/consts/user.rs to represent the maximum number of allowed invite requests.
• Refactor the code to replace the hardcoded value 10 with this new constant.
