Allow configuring different Max Age values for different paths/pages

<

Problem/Motivation

Currently, the module only allows assigning a single alternate Max Age value for multiple pages. There is no way to set different Max Age values for different individual pages. This limitation reduces the flexibility of the caching configuration, especially in cases where pages have varying levels of content volatility and caching needs.

Steps to reproduce

Install and enable the module that provides alternate Max Age configuration.

• Navigate to the module's configuration interface.
• Attempt to assign different Max Age values to different pages (e.g., /news, /contact, /dashboard).
• Observe that the configuration only supports a single alternate Max Age value applied globally or to a set of paths, with no per-path granularity.
