### Commit Summary
This pull request updates our coding guidelines to include a process for marking deprecated functions using metadata in ClojureScript.
This commit upgrades Shadow CLJS from 2.11.16 (released on Feb/21) to latest
2.25.0 (Jul/23), so ~1.5 years worth of upgrades. By upgrading shadow we
can finally use the latest major Clojure version 1.11.x.
Why upgrade shadow?
- Shadow CLJS controls the ClojureScript version we can use. In order to use the
latest major Clojure version we must upgrade Shadow CLJS.
- Shadow CLJS releases new versions very frequently, and if you take a look at
its changelog https://github.com/thheller/shadow-cljs/blob/master/CHANGELOG.md, you'll see
it had tons and tons of bug fixes over the years. I hope some of them help
improve the DX for certain contributors who recently reported issues with
it.
- Clojure 1.11 brings new features, bug fixes and even performance improvements
(although I think the performance mostly impacts Clojure on the JVM). See the
changelog https://github.com/clojure/clojure/blob/master/changes.md#changes-to-clojure-in-version-1110
Things that can be beneficial to us, or are interesting nonetheless:
- New :as-alias to be used in require, which is like :as but does not require
the namespace to load. This means namespaced keywords using :as-alias can't
cause circular dependency errors. This feature would very useful if we used
namespaced keywords, but we don't, so...
https://github.com/clojure/clojure/blob/master/changes.md#22-as-alias-in-require
- New macros run-test and run-test-var to run single test with fixtures and
report.
- New iteration function, useful for processing paginated data.

- New update-keys function: applies a function to every key in a map.
- New update-vals function: applies a function to every value in a map.
Examples for update-vals and update-keys. They should perform better than the
common reduce-kv approach since they use a transient data structure.
(let [m {:a 1 :b 2}]
(update-vals m inc)) ; => {:a 2, :b 3}
(let [m {:a 1 :b 2}]
(update-keys m name)) ; => {"a" 1, "b" 2}
Why change namespaces within __tests__ directories?
Any namespace with the word --tests-- throws an error, like the one below. I
didn't bother investigating why, so I changed the guidelines to reflect the new
convention. It's probably related to the double dashes in the name.
Namespace quo2.components.dividers.--tests--.divider-label-component-spec has a
segment starting with an invalid JavaScript identifier at line 1

Changes effect :json/rpc-call to accept on-success and on-error parameters
either as functions OR as re-frame event vectors. The changes are 100% backwards
compatible.
## Why?
Re-frame is very explicit in its documentation and its architecture, saying that
event handlers should be pure. Calling re-frame.core/dispatch in event handlers
makes them sort of stateful.
> So, you can "get away with it". But it ain't pure.

In status-mobile, arguably one of our most important effects (not to be confused
with event handlers) is :json-rpc/call, but at the moment, the on-success and
on-error values are expected to be stateful functions (e.g. usually used for
logging and dispatching subsequent events).
This creates two important problems:
1. The value returned by event handlers is more opaque and cannot be easily
inspected (for example using tap>, log/debug or just println). If we try to
inspect or log them, on-success and on-error will be printed as
#object[Function].
2. Testing event handlers using :json-rpc/call becomes an exercise of
frustration, because we can't simply compare the results of the event handler
with a good expected value, which is one of the big selling points of testing
pure functions.
### The testability of event handlers
> For any re-frame app, there's three things to test:

> - Event Handlers - most of your testing focus will be here because this is
> where most of the logic lives
> - Subscription Handlers - often not a lot to test here. Only Layer 3
> subscriptions need testing.
> - View functions - I don't tend to write tests for views.

So re-frame is saying event handlers should be pure, and that event handlers
should be tested.
In order to achieve the divine simplicity of testing event handlers as pure
functions, we need to make :json-rpc/call also accept on-success and
on-error as event vectors.
Good news is that there is a known pattern to solve this problem, e.g. used by
the library https://github.com/Day8/re-frame-http-fx.
The pattern is simple once we see it: behind the scenes, :json-rpc/call conj'es
the results of the RPC call into the event vectors on-success and on-error, and
:json-rpc/call dispatches the events itself. This eliminates the need for the
stateful dispatch call in event handlers.
- New section: Use [] instead of () in Reagent components: New section after
this comment https://github.com/status-im/status-mobile/pull/15005#discussion_r1098220176
- Updated section "Don't use percents to define width/height": reworded to
follow the style of the rest of the document.
- Update section "Accessibility labels": added example about avoiding dynamic
labels.
Update certain `style.cljs` files to more strictly follow our guidelines. Except for animations and theme colors, *style* functions should be pure.
It turns out `style` namespaces are well behaved and are almost perfectly following guidelines 🚀
The motivation for the PR came from this thread https://github.com/status-im/status-mobile/pull/14925#discussion_r1090485454
We are trasnferring the Apple app to the new Switzerland based Apple
development organization/team from the old Singapore one, and to make
this work we also need to update the development team ID.
This should fix the following failure:
```
Could not find App ID with bundle identifier 'im.status.ethereum'
You can easily generate a new App ID on the Developer Portal using 'produce':

This way the name of the repo makes at least some sense and
matches the `status-desktop` repo naming.
Also updated `status-jenkins-lib` since it also contained
references to `status-react` repo and job names.
