panel sorting and fuzzy filtering across all resource types

**Is your feature request related to a problem? Please describe.**
Lists in all panels are unordered, making it hard to prioritize or make sense of resources at a glance, especially with many services, images, or volumes. The current filtering behavior also falls short: searching "exited ", "exited (", "exited (127)" drops entries like "exited (127)", which is the opposite of what you'd want.

**Describe the solution you'd like**
1. **Sorting** — cycle through sort modes per panel (e.g. pressing `s`):
- **Services**: by `depends_on` order, status, or name
- **Containers**: by CPU/memory usage or creation time
- **Images**: by size or date
- **Volumes**: by size or usage count

The active sort mode would be shown in the panel header.

2. **Fuzzy matching for filters** — use fuzzy/substring search instead of exact match so that typing "exited" surfaces *all* entries whose status contains that word, including "exited (127)", "exited (1)", etc.

**Describe alternatives you've considered**
None

**Additional context**
I intend to open a PR for this — opening this issue first to get maintainer feedback on direction and keybinding choices before writing code.
