fix/projects: нормализация телефона-источника + понятная ошибка и подсказка

Косяк 02: поле телефона проекта типа call отвергало +7.., 8.., пробелы и скобки.
prepareForValidation в StoreProjectRequest и UpdateProjectRequest приводит номер
через PhoneNormalizer к канону 7XXXXXXXXXX без ведущего плюса, чтобы раздача
LeadRouter матчила без плюса. Финальная regex оставлена страховкой.
Кастомные messages по signal_type: ошибка с примером формата, без имени Источник.
Фронт: постоянная подсказка под полем в NewProjectDialog и ProjectDetailsDrawer.
TDD: ProjectPhoneNormalizationTest 8 кейсов, GREEN. Проверено глазами на 8000.
