panic fix: the panic was caused by trying to truncate a block that doesn't exist. This would fail silently before. The fix allows us to truncate to a sequence where the whole message block should be removed.
remove index.db first: part of the issue was that an old/ahead index.db would be preserved if we'd be hard killed halfway during truncation. Now remove that index first, so we recover based on the messages normally, and don't try to hold a last seq that's ahead and should have been truncated.
truncate to previous correct entry: the Raft logic would not truncate to the correct index on startup (off-by-one), this would result in the Wrong index and Resetting WAL state issues.
