This commit fixes the background crashes with termination code
0xdead10cc.
Those crashes were caused by the fact that NostrDB was being stored on
the shared app container (Because our app extensions need NostrDB
data), and iOS kills any process that holds a file lock after the
process is backgrounded.
Other developers in the field have run into similar problems in the past
(with shared SQLite databases or shared SwiftData), and they generally
recommend not to place those database in shared containers at all,
mentioning that 0xdead10cc crashes are almost inevitable otherwise:

- https://inessential.com/2020/02/13/how_we_fixed_the_dreaded_0xdead10cc_cras.html
Since iOS aggressively backgrounds and terminates processes with tight
timing constraints that are mostly outside our control (despite using
Apple's recommended mechanisms, such as requesting more time to perform
closing operations), this fix aims to address the issue by a different
storage architecture.
Instead of keeping NostrDB data on the shared app container and handling
the closure/opening of the database with the app lifecycle signals, keep
the main NostrDB database file in the app's private container, and instead
take periodic read-only snapshots of NostrDB in the shared container, so as
to allow extensions to have recent NostrDB data without all the
complexities of keeping the main file in the shared container.
This does have the tradeoff that more storage will be used by NostrDB
due to file duplication, but that can be mitigated via other techniques
if necessary.

This is a large refactor that aims to improve performance by offloading
RelayPool computations into a separate actor outside the main thread.
This should reduce congestion on the main thread and thus improve UI
performance.
Also, the internal subscription callback mechanism was changed to use
AsyncStreams to prevent race conditions newly found in that area of the
code.

This commit fixes a regression on the highlighter and share extensions,
which was caused by a change in the code's architecture, which required
the network manager to be initialized.

This commit implements a new layer called NostrNetworkManager,
responsible for managing interactions with the Nostr network, and
providing a higher level API that is easier and more secure to use for
the layer above it.
It also integrates it with the rest of the app, by moving RelayPool and PostBox
into NostrNetworkManager, along with all their usages.
Changelog-Added: Added NIP-65 relay list support
Changelog-Changed: Improved robustness of relay list handling

1. While sharing images/videos from Apple's Message app, the file will be treated as a Link with file-url. The if-else ordering will help to fix the issue.
2. While sharing image from Signal and Facebook app, the file being received is an UIImage and error is being sent. This PR fixes the issue.
