Commit Message

fix(cli): detect dead db connections (CLI-2207) (#6277)

## TL;DR

fixes `supabase db reset` and `supabase start` hanging forever with no
error when the database connection dies while migrations are being
applied

## whats broken?

node-postgres silently discards every protocol frame once a socket stops
being writable, while still reporting the write as successful, so the
whole batch goes nowhere and the CLI waits forever on a reply the server
was never asked for

it also leaves TCP keepalive off by default, where the Go CLI's driver
had it on, so a peer that dies without a FIN or RST is never noticed
either

## fixed now by:

- failing a batch that never reached the wire as a connection error,
carrying the driver's own reason instead of blaming the migration's
first statement
- discarding that pooled connection, so the next batch redials instead
of writing into the same dead socket
- turning TCP keepalive on for every connection the CLI opens, so a
silently dead peer is eventually detected instead of waited on

a server that stays alive but never answers still waits, matching the Go
CLI, since that is indistinguishable from a long running statement

## ref:
- closes: https://github.com/supabase/cli/issues/6244
