Improved organization of settings

We've just updated the various settings pages in Church Social to make them more organized, more discoverable, and more clear on who has access to them.

The "My Profile" page has been moved out of the "Settings" area, and now has its own link in the user dropdown menu. We've also split it up into three different pages — "Details", "Security", and "Notifications". This page was quite large before, so this makes navigating these settings a little more manageable.

The "Settings" pages, like the church settings, message settings, prayer settings, etc., are now only ever accessible by administrators. Previously users with certain roles were able to access some of these pages. For example, sermon editors could access the sermon settings page, and librarians could access the library settings page. This is no longer the case, and only administrators can access these pages.

For any settings that users with specialized roles need to change, we've moved these out of the settings area into their respective sections of the app. For example:

• Treasurers can now access the receipt settings on a new "Settings" page in the giving area. This currently only applies to churches in Canada and New Zealand.
• Sermon editors can now edit the podcast settings via a new "Podcast feed" dialog found on the sermons page.
• Sermon editors can now access a new "Integrations" dialog on the sermons page that explains how to integrate sermons into your church's website.
• Sermon editors can now edit the livestream embed code on the livestream page.
• Librarians can now access the "Delete library" option from the library page, and we've made sure to add an extra level of confirmation to prevent anyone accidentally doing this.

So, in summary:

1. There's a dedicated new "My Profile" section.
2. Only administrators can access the "Settings" section moving forward.
3. Role-specific settings are now found in their respective areas of the app.
