Copy startup terminal (#5585)

* Add copyTerminal translation key

* Add copy terminal button with select all functionality

* Remove copy button from error view button group

* Add hover-based copy button overlay to terminal

* Fix clipboard copy implementation in BaseTerminal

* Add 'Copy all' tooltip to terminal copy button

* Fix copy button to be away from right hand side

* Update copy button to respect existing selection

- Copy only selected text if any exists
- Copy all text and clear selection if nothing selected
- Update tooltip to reflect new behavior

* Add dynamic tooltip showing actual copy action

- Show 'Copy selection' when text is selected
- Show 'Copy all' when no text is selected

* Remove redundant i18n

* Fix aria-label to use dynamic tooltip text

* Remove debug console.error statements from useTerminal

Clean up debug logging added during development:
- Remove selection change debug logging
- Remove focus state debug logging
- Remove keyboard event debug logging
- Remove copy/paste debug logging

* Remove redundant keyboard handling from useTerminal

The rebase commit already fixed basic copy/paste.
Removed only the complex keyboard event handling that
duplicates the rebase fix. Kept the valuable UI features:
- Hover copy button overlay
- Right-click context menu

* Use Tailwind transition classes instead of custom CSS

Replace custom .animate-fade-in with standard Tailwind
transition-opacity duration-200 classes

* Use VueUse useElementHover for robust hover handling

Replace manual mouseenter/mouseleave events with VueUse
useElementHover composable which properly handles all
edge cases including mouseout and interrupted events

* Move tooltip to left of button

Relieves squished tooltip

* Simplify code

* Fix listener lifecycle management

Consolidate setup into single onMounted block instead
of creating unnecessary duplicate lifecycle hooks

* Replace any type with proper IDisposable type

* Refactor copy logic for clarity

* Use v-show for proper opacity transitions

* Prefer optional chaining

* Use useEventListener for context menu

* Remove redundant opacity classes

* Add BaseTerminal component tests

* Use pointer-events for button interactivity

* Update tests for pointer-events button behavior

* Fix clipboard mock in tests

* Fix test expectations for opacity classes

* Simplify hover tests for button state

* Remove low-value 'renders terminal container' test

* Remove non-functional 'button responds to hover' test

* Remove implementation detail test for dispose listener

* Remove redundant 'tracks selection changes' test

* Remove obvious comments from test file

* Use cn() utility for conditional classes

* Update tests-ui/tests/components/bottomPanel/tabs/terminal/BaseTerminal.spec.ts

Co-authored-by: Alexander Brown <drjkl@comfy.org>

* [auto-fix] Apply ESLint and Prettier fixes

* Remove 'any' types from wrapper and terminalMock variables

Add assertion to verify onSelectionChange was called

* Move mountBaseTerminal factory to module scope

* Rename test file

- Current consensus is .test.ts for component files

* Update src/components/bottomPanel/tabs/terminal/BaseTerminal.vue

* nit
