Add i18n support with inlang/paraglide for English and Polish

[Copilot]

Extracted all hardcoded UI strings to enable multi-language support. Configured inlang with paraglide-js for type-safe, compile-time translations.

Changes Made

• Translation infrastructure: Configured inlang with local plugins, added ~125 translation keys to messages/en.json and messages/pl.json
• Component updates: Replaced hardcoded strings with m.{key}() calls across 15+ components (map UI, auth flows, dialogs, forms)
• Paraglide integration: Auto-generates TypeScript functions from JSON translation files at build time

Translation Keys Added

• Profile settings: title, subtitle, tabs, labels for display name, email, password fields, profile picture section
• User menu: Profile, Events, Settings, Logout items
• Event management: About section, Schedule section, Event Occurrence, "No upcoming dates", description label
• Common actions: Remove, Change, Upload, Saving, Updating, Save Changes, Add
• Error messages: Failed to load address, Unknown location
• Date picker: Internationalized placeholder with fallback
• Theme customization: Theme color label

Components Updated

• user-menu.svelte - Translated menu items
• profile-dialog.svelte - All labels, buttons, and profile picture section
• event-details-content.svelte - About and Schedule headers, unknown location fallback
• events-dialog.svelte - "No upcoming dates" message
• new-event-overlay.svelte - Add button and Description label
• date-time-picker.svelte - Internationalized placeholder
• map-point-cta.svelte - Unknown location and error messages
• sidebar-rail.svelte - Translated aria-label and title attributes
• color-picker.svelte - Translated label and placeholder

Coverage

Event management • Authentication • User profile • Search • Dialogs • Forms • Notifications • Error messages • Theme customization

Original prompt

Find all strings in the frontend code and add them to the translations in inlang. Then make sure the frontend elements use the strings. Also, follow the instructions in @lythar/Cartesian/files/.github/instructions/AGENTS.instructions.md

@copilot I've update the repo with a few commits, so you should update the translations to all the new elements too.

@copilot I've update the repo with a few commits, so you should update the translations to all the new elements too.

Added translation keys for all newly discovered hardcoded strings in commit 6a688e4. This includes:

• Profile settings (title, subtitle, tabs, labels for display name, email, password fields)
• User menu items (Profile, Events, Settings, Logout)
• Event details (About section, Schedule section, Event Occurrence)
• Common actions (Remove, Change, Upload, Saving..., Updating..., Save Changes)
