Improve env up/halt live status rendering and gate visibility

[giubacc]

Problem

Environment lifecycle status output can be clearer and more scalable:

1. up env and halt env should provide consistent live progress behavior.
2. Gate visibility does not scale well when many probes are required.
3. It’s not always obvious when gates are pending, passed, or failed.

Proposal

1. Use one shared live wait/render flow for both up env and halt env.
2. Add a compact first Gates column with glyphs only (one glyph per required gate).
3. Add optional detailed probe-gate names in a last column when --details is enabled.
4. Sort probe names alphabetically in details view.
5. Color gate states live:
   • pending: dim
   • pass: green
   • fail: red
6. Keep non-terminal mode deterministic (no hanging loops).

Acceptance criteria

1. up env and halt env both show live progress tables.
2. Gates are visible in compact form and update live.
3. --details shows sorted probe names with live status colors.
4. Behavior is stable in both terminal and non-terminal runs.
5. Tests and type checks pass.
