docs: reframe the intro as an all-in-one toolkit with a 5-item overview

Replace the 'workbench' tagline and 4-item bullet list with 'all-in-one'
(всё в одном) and a 5-item overview that adds the file manager (decoded
views, FCP/FCI and access rules) and names the APDU/OTA/simulator/
profiler tools the same way in both languages.

+SIMple is an all-in-one toolkit for UICC/SIM card specialists: an offline HTML/JS frontend (PWA — a Progressive Web App) and a local card server ([`pysim-simple-server`](pysim_simple_server/), a pySim/PC-SC wrapper). It packs a wide set of card tools:
 
-- **APDU workbench** — SIM/USIM RFM and Expanded Script builders (TS 102 226), GlobalPlatform RAM commands, a C-APDU/R-APDU parser and a response decoder (ISO 7816 / TS 102 221 / GP);
-- **OTA lab** — SCP80 secured packets (TS 102 225) and Java Card RAM installation, plus the terminal side of HTTP OTA (SCP81): BIP channel emulation, a PSK TLS administration server and APDU script execution;
-- **Phone/CAT simulator** — SIM Toolkit menu browser, proactive command / event handling, TERMINAL PROFILE editing and the C-AT dialogue log;
-- **Card profiler** — filesystem capture (profiles and immutable snapshots with timings), exact snapshot comparison and FCP/FCI decoding.
+- **File manager** — browse and edit files, including in decoded form, with FCP/FCI and access-rule decoding;
+- **APDU builder and parser** — SIM/USIM RFM, RAM in the compact format, Expanded Format Scripts (TS 102 226), a C-APDU/R-APDU parser and a response decoder (ISO 7816 / TS 102 221 / GP);
+- **OTA lab** — TS 102 225 / GSM 03.48 secured packets (SCP80) for sending through a card reader, and HTTP OTA (SCP81): BIP channel emulation and a PSK-TLS server for working through a card reader;
+- **Simulator** — an STK menu browser, proactive command and event handling, TERMINAL PROFILE editing, and test scripts for checking any scenario;
+- **Profiler** — filesystem snapshot capture, comparing snapshots to each other and to the rule sets a profile must satisfy.
 
 **Demo:** [simsimple.ru](https://simsimple.ru) — the frontend alone, for experimenting. Install the server (below) for card-reader functions.
