Add pagination for quote and history lists

[DemonGiggle]

Summary

• add count and limit/offset pagination for recall history through the store, engine, app, web, and client layers
• switch TUI quote/history list pages to paged loading with page metadata and left/right page navigation
• switch the desktop/web frontend quote/history lists to previous/next paging, while preserving full-library quote loading only when a library filter is active
• add history pagination tests and update TUI expectations for the clarified visible-selection wording

Validation

• go test ./...
• npm --prefix frontend run build

Fixes #72

Code Review

This pull request implements pagination for recall history and quotes across the database, engine, API, and user interfaces (TUI and frontend). It introduces new methods for counting records and fetching specific pages using limit and offset parameters. Feedback was provided to refactor the clampPageOffset helper function in the TUI to improve code clarity and maintainability by reusing existing pagination logic.

The calculation for maxOffset is a bit dense. Reusing the logic from the totalPages function can make this function's intent clearer and improve maintainability.

func clampPageOffset(totalCount int64, pageSize, offset int) int {
	if totalCount <= 0 || pageSize <= 0 {
		return 0
	}
	if offset < 0 {
		offset = 0
	}

	// Reuse logic from totalPages for clarity.
	numPages := int((totalCount + int64(pageSize) - 1) / int64(pageSize))
	maxOffset := (numPages - 1) * pageSize
	if offset > maxOffset {
		return maxOffset
	}

	return offset
}
