feat: make the skills verification catalog budget configurable per server (#2294)

Adds a Skills section to Server Settings with Maximum Number of Skills and
Maximum Catalog Size fields, defaulting to SKILL_MAX_CATALOG_SKILLS (256) and
SKILL_MAX_CATALOG_BYTES (64 MiB). The values persist as skillCatalogMaxSkills /
skillCatalogMaxBytes on the server's mcp.json entry (omitted at the default),
are validated as positive integers by the /api/servers routes, and are read by
verifySkills through getServerSettings(), so the CLI's --verify and the TUI
Skills pane both honor them.
