Fixes 'error while parsing protocol' HanaException by supporting
SSL/TLS encryption, Multi-Tenant Database Container (MDC) database
name, and arbitrary additional connection parameters.
- HanaServer model: added DatabaseName, UseSsl, ValidateCertificate,
AdditionalParams fields + BuildConnectionString() helper
- HanaQueryService: accepts HanaServer directly, uses
BuildConnectionString() for full parameter support
- AppDbContext: added EnsureSchema() method that uses PRAGMA table_info
+ ALTER TABLE ADD COLUMN to add the new fields to existing SQLite
databases without losing data (EnsureCreated does not update schema)
- Program.cs: calls EnsureSchema on startup before seeding
- Standorte.razor: server dialog now exposes DatabaseName, UseSsl,
ValidateCertificate, AdditionalParams with helper texts; test
connection uses new signature
