fix(tor): clear remembered-approval window on user TorType toggle

Once the user picked "Use regular connection" after a 60s stuck-Connecting
prompt, `lastBypassApprovalMs` was persisted to DataStore for an hour. Inside
that window the connection-failure flow silently flipped `sessionBypass = true`
on every later Connecting span instead of re-prompting, which caused the
status flow to call `service.stop()` and emit `Off` regardless of the user's
`TorType`. The DataStore-backed approval survived force-stop, and toggling
Tor off/on only cleared the in-memory `sessionBypass` half — so the next
bootstrap attempt re-triggered the silent bypass after 60s and the user was
trapped until wiping app data.

Any user-initiated `TorType` change now wipes both halves: the in-memory
`sessionBypass` flag and the persisted approval. The next stuck-Connecting
span will surface the dialog again so the user has a real choice instead of
a silent fall-back to direct.
