refactor(tui): Change Fold/unfold to Open/close

[narnaud]

Fold/unfold was confusing with the command Fold just close. Use the
terms Open/close: same meaning, but different from existing commands.

Inline comments:
In `@docs/src/commands/tui.md`:
- Line 37: Complete the navigation terminology rename: in
docs/src/commands/tui.md lines 37 and 47, replace fold/unfold wording with
open/close terminology; in specs/020-tui.md lines 61, 63, and 66-71, rename the
section and replace folding, unfolding, unfolds, and folds consistently with
open/close terminology, reserving “Fold” for the command.

In `@src/tui/app.rs`:
- Line 2020: Correct the Open/close hint ordering so left/← indicates close and
right/→ indicates open. Update the status-bar text in src/tui/app.rs at lines
2020-2020, the corresponding documentation entries in docs/src/commands/tui.md
at lines 26-26 and 36-36, and the specification in specs/020-tui.md at line
41-41; update the expected status-bar text in src/tui/app_test.rs at line
2173-2173 to match.
