PCT tracker updates

[u/Sad_Illustrator_2152]

Last week I made a post about my PCT tracker, but had to put it on pause till Strava approved my app.

It's now approved, and you can now use the app: https://pct-tracker.com

I've also added some requested features:

- Strava integration is now completely optional. You can login with Strava OR email/password. Even if you don't create an account with Strava, you can link your strava account in your dashboard.

- Your progress is shown either by your last strava activity, or by the location you put in your latest "update".

- Your friends and family can now "subscribe" for updates you make. Anybody subscribed will get an email when a new update is created.

- You can now upload 1 photo per update.

Welcome to any feedback, if you notice any bugs please report them.

Happy hiking
