# Objective

The settings panel rendered as a persistent bar above the table, always
taking up vertical space even though most of its controls (text
alignment, filter sort order, multiline rows, dev-only toggles) are
rarely touched. @Anthony-Eid suggested reworking it into popover

## Solution

Replaced the always-visible settings panel with a single settings icon
button (next to the row-identifier toggle) that opens a popover menu
with the same controls, grouped under headers:
- Text Alignment, Filter Sort, Display
- and (behind `dev-tools`) Rendering Mode / debug toggles.

Frees up the row of vertical space previously occupied by the panel.
Similarly how it's done in git pannel


## Testing

`cargo check -p tabular_data_preview` and `--features dev-tools` both
build clean; `./script/clippy` clean.
Manually opened the popover and toggled each setting (alignment, filter
sort, multiline rows) to confirm they still apply and persist while the
popover stays open.
