feat: add Table column visibility, order, and resize options

[mentonin]

Summary

• Partial fix for Custom column/header selection and width #2008: column visibility, reorder, and resize - no persistence of any kind.
• Fixes Table columns should have fixed/consistent size #420 content-independent widths (no jump on sort/pagination)
• Shared useLayoutTable entry point drives Tree, Hardware, Issues, Builds, Boots, and hardware tree picker tables.
• Interior resize handles redistribute width between neighbors (table width fixed); outer edges can grow/shrink the table. Manual resize ignores maxWidth.
• Status column minWidths sized for Build (3-digit), Boot (4-digit), and Test (5-digit) counts.
• Tests / IndividualTests tables intentionally left out (pending feat: unify hierarchical test table grouping #2030 grouping rework). Persistence and share/export URL are follow-ups.

Test plan

• Tree / Hardware / Issues listing: Columns menu toggles and reorders; row-header columns
  stay leftmost and visible
• Drag interior handles: neighboring columns trade width; table width unchanged
• Drag outer (first left / last right) handles: table width changes; horizontal scroll when needed
• Reset marker clears manual width for that column
• Sort / paginate: column widths do not jump with content
• Build/Boot/Test status badges fit 3/4/5-digit counts at default mins without clipping
