[FEAT] Node Managment (#1895)

* [FEAT] Node Managment

feat: node dashboard channels and transactions
fix: update channel variables
better types
refactor ui
add onchain balances and backend_name
mock values for fake wallet
remove app tab
start implementing peers and channel management
peer and channel management
implement channel closing
add channel states, better errors
seperate payments and invoices on transactions tab
display total channel balance
feat: optional public page
feat: show node address
fix: port conversion
feat: details dialog on transactions
fix: peer info without alias
fix: rename channel balances
small improvements to channels tab
feat: pagination on transactions tab
test caching transactions
refactor: move WALLET into wallets module
fix: backwards compatibility
refactor: move get_node_class to nodes modules
post merge bundle fundle
feat: disconnect peer
feat: initial lnd support
only use filtered channels for total balance
adjust closing logic
add basic node tests
add setting for disabling transactions tab
revert unnecessary changes
add tests for invoices and payments
improve payment and invoice implementations
the previously used invoice fixture has a session scope, but a new invoice is required
tests and bug fixes for channels api
use query instead of body in channel delete
delete requests should generally not use a body
take node id through path instead of body for delete endpoint
add peer management tests
more tests for errors
improve error handling
rename id and pubkey to peer_id for consistency
remove dead code
fix http status codes
make cache keys safer
cache node public info
comments for node settings
rename node prop in frontend
adjust tests to new status codes
cln: use amount_msat instead of value for onchain balance
turn transactions tab off by default
enable transactions in tests
only allow super user to create or delete
fix prop name in admin navbar
