fix(site): polish table alignment for workspace proxies (#24538)

Fixes alignment issues in the workspace proxies table.

## Changes

- **Status column alignment**: Removed `text-right` from the Status
column header and the `justify-end` flex wrapper from status cells.
Status indicator dots now align consistently across rows regardless of
text width ("Healthy" vs "Not reachable").
- **Error/warning text alignment**: Changed padding from `px-12` (48px)
to `px-14` (56px) so error/warning messages align with proxy name text,
which starts after cell padding (12px) + avatar (32px) + gap (12px) =
56px.
- **colSpan fix**: Corrected `colSpan={4}` to `colSpan={3}` to match the
actual number of table columns.
