Persistent nodedb

[philon-]

Description

This is a draft PR that adds persistence of node database. This is the first step towards safe persistence of messages, telemetry and so on.

This is very much a rough draft, I just wanted it here so that we can keep track on the progress, what remains and what should (and should not) be part of this PR.

Still remaining before this can be merged:

• Wipe persisted database when the nodedb reset option is called
• Update PKI regen dialog to allow reuse when nodes have mismatching keys
• (?) CommandPalette option to disconnect & wipe storage
• Tests

Related Issues

Changes Made

Major:

• Refactored deviceStore by breaking the monolith apart and bringing all nodeDB methods into its own nodeDBStore
• Adjusted the DeviceContext so that instead of passing the Device object along, we only pass the nodenum and get the correct Device and NodeDB objects from their respective hooks useDevice and useNodeDB
• Rewrote the JSON serializer previously used for the messageStore to allow more special handlers, since more datatypes need specific (de)serialization.
• Defined NODEDB_RETENTION_NUM (currently 10) which defined how many separate devices' nodeDBs should be saved before cycling them out.
• Tests for nodeDB store, indexDB handler

Minor:

• Updated useFavoriteNode and useIgnoreNode to use the separate device and nodedb stores.
• Updated existing tests

Testing Done

Pull Request Overview

This PR implements persistence for the node database by separating node-related functionality from the monolithic device store into a dedicated nodeDB store. The refactoring improves data organization and enables persistent storage of node information.

Key Changes

• Extracted node-related methods from the device store into a separate nodeDB store with persistence
• Refactored device context to use device IDs instead of device objects
• Rewrote the JSON serializer to support additional data types like Map and Uint8Array
