cmd/utils/app: fix seg reset not removing chaindata (#20908)

- \`seg reset\` regressed in #18273: \`removeLocal\` from the CLI is
wired into \`reset.Reset.RemoveUnknown\` but not \`RemoveLocal\`, which
gates chaindata + Heimdall/PolygonBridge DB removal in
\`db/datadir/reset/reset.go\`. Result: \`seg reset\` no longer touches
chaindata at all.
- Library-level \`TestResetChaindata\` exists but sets \`RemoveLocal:
true\` directly, so the CLI plumbing was uncovered.

closes #20260
