Feature: Tiling Watermark

[Anubhav-Mondal]

Add support for repeating/tiled watermarks that cover the entire page, for both text and image modes.

Proposed Solution

Add a tile toggle to the existing addWatermark function. When enabled, calculate a grid of positions across the page using tileSpacingX and tileSpacingY and draw the watermark at each cell instead of a single fixed position. Expose spacing and stagger controls in the UI.

Suggested Label

"NSoC'26", "enhancement"

Hey @JhaSourav07 , thanks for assigning this to me! Excited to work on it. Just a quick heads-up: for NSoC point tracking, could you please add a difficulty/level label to this issue when you get a chance? Thanks a lot!
