To have vim style CRUD for alarms in sqlite database.

The database scheme:
"""
CREATE TABLE alarms (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    name TEXT NOT NULL,
    description TEXT,
    time TEXT,  -- HH:MM format for simple alarms
    trigger TEXT NOT NULL,  -- Cron expression or 'once'
    sound_path TEXT NOT NULL,
    enabled BOOLEAN DEFAULT 1,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
    last_triggered TIMESTAMP,
    snooze_count INTEGER DEFAULT 0
);

CREATE TABLE alarm_history (
    id INTEGER PRIMARY KEY AUTOINCREMENT,
    alarm_id INTEGER,
    triggered_at TIMESTAMP,
    dismissed_at TIMESTAMP,
    snoozed_count INTEGER,
    FOREIGN KEY (alarm_id) REFERENCES alarms(id)
);

CREATE TABLE settings (
    key TEXT PRIMARY KEY,
    value TEXT
);
"""

To be run in Linux terminals.
