Enforce pagination bounds on search list endpoints

[RUKAYAT-CODER]

Overview

The list endpoints in src/search/search.controller.ts accept pagination parameters (page/limit/offset/cursor). Ensure a sane maximum page size is enforced and invalid values are rejected, so a client cannot request an unbounded number of rows (a memory/DoS and performance risk) or pass negative/non-numeric values.

Specifications

Features:

• Page size is clamped to a documented maximum.
• Invalid pagination values (negative, zero, non-numeric, over-max) are rejected with 400.
• A consistent default page size is applied when none is provided.

Tasks:

• Add/replace pagination inputs with a validated pagination DTO (class-validator: @IsInt, @Min, @Max) under src/search/dto.
• Apply the DTO to the list handlers in src/search/search.controller.ts and clamp/validate the limit.
• Document the default and maximum page size.

Impacted Files:

• src/search/search.controller.ts
• src/search/dto/ (pagination DTO)

Acceptance Criteria

• Requesting an oversized limit is either clamped or rejected with 400 — never served unbounded.
• Invalid pagination values return 400.
• A default page size applies when parameters are omitted.
