fix: make component drawer table rows inert, move selection to the name control

[marekdano]

Closes #59

Summary

• Drop onClick/onKeyDown/tabIndex/cursor-pointer and the row-level focus ring from ToolsTable, ResourcesTable, and PromptDefinitionTable — rows are
  now inert, matching ServersTable.
• Move selection to the name cell: it's now a ghost button that calls onSelect*, underlines on hover, and is keyboard-activatable natively, removing the need
  for the 20 stopPropagation() calls that only existed to shield row controls from the row's own click handler.
• Wrap each ID/URI text + copy button pair in a hover group so the whole cell lifts together (text-muted-foreground → text-foreground) instead of only the
  icon button reacting.

Test plan

• Repointed the ~10 unit tests (across ToolsTable, ResourcesTable, PromptDefinitionTable, plus one each in ToolDetailsPanel and PromptDetailsPanel)
  that asserted row-click/row-keyboard/cursor-pointer behavior at the new name button.
• npx vitest run — 3054 passed, 1 skipped.
• npx playwright test e2e/tools.spec.ts e2e/resources.spec.ts e2e/prompts.spec.ts — 67 passed, no changes needed (specs drive selection via the overflow
  menu, not row clicks).
• tsc --noEmit and eslint clean on changed files.
