feat(supabase): add database output filtering

[esestamparia]

Summary

• add safe output filtering for selected supabase db and supabase migration list commands
• register direct, npx, pnpm, and pnpx discovery and rewrite paths
• preserve raw output for interactive, remote reset, terminal SQL diff, errors, and unknown formats
• redact sensitive command arguments from RTK history and provide full-output guidance when truncating

Supported filters

• supabase db lint
• supabase db push --yes
• supabase db push --dry-run
• supabase db diff with -f, --file, -o, or --output
• supabase db reset --local
• supabase migration list

Safety

Interactive db push, terminal SQL output from db diff, remote or linked resets, failures, and unknown formats remain passthrough. Sensitive tokens, passwords, and database URLs are sanitized in history.

Validation

• cargo fmt --all --check
• cargo clippy --all-targets
• cargo test (2514 passed, 8 ignored; integration guards 11 passed)
• targeted filter and discovery tests
• manual passthrough checks
• git diff --check
• representative output reduction: 66.9%

Relates to #1995
