feat(steam_workshop): production rewrite with full admin profile page and server settings

- module.php: bump db_version to 2; full v2 schema in install_queries[0]; ALTER TABLE migration in install_queries[2] adding 11 new profile columns plus server_workshop_settings table
- WorkshopRepository: expand saveProfile() with all new fields (steam_app_id, steamcmd_login_mode, steamcmd_path, mod_separator, copy_keys, key paths, pre/post scripts, validation_notes); add nullOrStr helper; add server settings CRUD (getServerSettings, saveServerSettings, recordUpdateResult, setUpdateQueued, listQueuedUpdateHomes); update insertOrUpdateMod with custom_folder; update listAllEnabledMods to select new columns
- WorkshopProfileController: full extractProfileData() with all new fields; validateProfileData with folder template check
- views/admin/profile_form.php: full rewrite – all required fields (steam_app_id, workshop_app_id, login mode, SteamCMD path, OS, cache path, install path, folder naming dropdown, launch params, mod separator, copy method, copy keys with JS show/hide, key paths, pre/per-mod/post bash scripts with DayZ example, validation notes, config file template)
- views/admin/profiles.php: updated list view columns (App IDs, Login, Method)
- WorkshopInstaller.php: full rewrite with %var% template support (+ legacy {var} compat); buildTemplateVars() resolves all 14 variables; pre/post script execution; triggerSteamCmdDownload uses new profile fields; copyKeys helper
- WorkshopModController: add save_settings and queue_update POST actions; handleModsPage loads serverSettings + allProfiles
- views/user_workshop_mods.php: full rewrite – server settings form (enable, profile selector, update mode, restart behavior), update status grid (status/error/time/success time), queue update button, mod table with custom_folder column and toggle/order auto-submit
- lang/en_US.php: ~80 new string keys for all v2 fields
- steam_workshop.css: new v2 styles (3-col grid, script textarea, status grid, server settings card, badges)"
