* fix: derusting tor implementation

Instead of rust-based Arti I've moved back to the
OG C++ tor implementation.
This fixed all issues we had with Tor.
- onion services now work
- all requests are going through without random errors
- we don't have to navigate a maze of multiple forks of multiple packages
- fully working `torrc` config file (probably will be needed for Tari).
- logging for Tor client
- and so on.

feat: network logging tab
feat: use built-in proxy on Tails - this should resolve all issues for Tails users (needs testing though)

* fix conflicts with main
bump https to fix build issue
relax store() call

* fix(cw_wownero): tor connection
fix(tor): connection issues

* fix(cw_evm): add missing chainId
fix(cw_core): solana rpc fix

* feat: mark tor as experimental
fix: drop anonpay onion authority
fix: drop fiatapi onion authority
fix: drop trocador onion authority
fix: disable networkimage when tor is enabled
fix: handle cakepay errors gracefully

* fix re-formatting [skip ci]

* changes from review

* Delete android/.kotlin/sessions/kotlin-compiler-2468481326039681181.salive

* fix missing imports

* Update pubspec_base.yaml
