Mobile push notifications + HCB notifications revamp

[scooterthedev]

I've been speaking to @thedev132 today about HCB Mobile notifications and to get this done we need to properly revamp HCB's end of notifications which has been discussed before but never happened. This issue will be sub-divided into 2 main sections for now:

1. HCB's notification panel. Right now, this panel is quite bland and doesn't allow the user to properly customize a varerity of options which are quite basic. As discussed in this old issue https://github.com/hackclub/hcb/issues/5367#issuecomment-2019199118, we would need to develop a proper UI that allows users to customize as much as possible without over-cluttering the screen with 2 million options. Ideally, we want the user to be able to customize getting SMS, Email, HCB Mobile notif's for major categories such as:

• Transfers, Checks, Disbursements, Reimbursements, Team updates etc
• Comments
• Only your transaction or all transactions under your orgs.

Figuring out how this can be developed can be discussed further later though figuring out how the MVP for delivery frequencies along with how we will handle all of this cleanly could be handled first.

2. HCB Mobile Integration. To be able to handle notifications via HCB Mobile, we will need to use HCB as a server being able to use the current notification settings set by the user, and relay it down to the HCB Mobile app along with handling the click within the app. For this to happen, we can use a library like https://github.com/expo-community/expo-server-sdk-ruby which will be able to interface with HCB Mobile's end (https://docs.expo.dev/versions/latest/sdk/notifications/). Though this is still a far away ahead until the main HCB's notification's section gets revamped.

Hi @scooterthedev! I'd love to involve you here. As you pointed out, there are two sections:

1. Notification configuration/settings and infrastructure
2. Integration into HCB Mobile for push notifications

We'll need to handle 1️⃣ before we can tackle 2️⃣. I've spent some time thinking about how to make HCB notifications more configurable; however, the toughest part is the UI/UX of making all these configurations. It needs to be feature-full, but also simple and non-cluttered.

If you'd like to start brainstorming/mocking up a front-end UI/UX for this, i'd really appreciate it. Feel free to share your thoughts and designs in https://github.com/hackclub/hcb/issues/5367#issuecomment-2019199118 and ping me on Slack to make sure i see it (sorry, there are a lot of github notifs).
