Involves the migration of all MissingMaps API endpoints to utilize the endpoints provided by ohsomeNow stats. The changes encompass four distinct sections, namely homepage stats, project-level stats, user-level stats, and TM level stats.

Removed the definitions of specific API endpoints, such as `TM_HOMEPAGE_STATS_API_URL` and `TM_USER_STATS_API_URL`, from the environment configuration. A new approach was implemented by introducing a new base URL for ohsomeNow (`OHSOME_STATS_BASE_URL`). This new structure enables the specification of endpoints at a component level, as opposed to being bound to the environment configuration.

- Introduce a new component, `StatsTimestamp`, responsible for displaying timestamps with tooltips. This component accepts a `messageType` prop to determine whether to show a generic or project-specific message. The inconsistent icon usage has been resolved, now consistently using an info icon.
- Reorganized the codebase by removing timestamp implementations from the User Contributions and Project Stats components. Instead, these components now utilize the newly introduced `StatsTimestamp` component for timestamp display.
- Integrated the `StatsTimestamp` component into the Total Features section of the overall statistics page.
